A set of pens sells for $5.25 and costs $1.80 to make. Forty percent of the profit (the difference between the purchase price and the amount it costs to make) from each set of pencils goes to a school. If 1200 sets are sold, what is the amount of money that will go to the school?

Answers

The amount of money that will go to the school is $ 3816.00

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The sale price of set of pens = $ 5.25

The cost price of set of pens = $ 1.80

The profit of pens = sale price of set of pens - cost price of set of pens

= $ 5.25 - $ 1.80

= $ 3.45

Now , the equation will be

Forty percentage of profit = ( 40 / 100 ) x $ 3.45

= $ 1.38

The amount that will go to the school =
Forty percentage of profit + cost price of set of pens

The amount that will go to the school for 1 set of pen = $ 1.38 + $ 1.80

= $ 3.18

The equation will be ,

Now , the total number of sets of pens sold = 1200

And , the total cost price of 1200 sets of pens =
cost price of set of pens x 1200

The total cost price of 1200 sets of pens = $ 1.80 x 1200

= $ 2160

The total profit of 1200 sets of pens = Forty percentage of profit x 1200

= $ 1.38 x 1200

= $ 1656

Therefore , the amount that will go to the school for 1200 sets of pens =
total cost price of 1200 sets of pens + total profit of 1200 sets of pens

The amount that will go to the school for 1200 sets of pens
= $ 2160 + $ 1656

The amount that will go to the school for 1200 sets of pens = $ 3816

Therefore ,

The amount that will go to the school = $ 3816.00

Hence , The amount of money that will go to the school is $ 3816.00

PLEASE HELP IT WOULD BE VERY MUCH APPRECIATED! Last year, James earned £1,600 per month.
This year, he's had a 2% increase in his monthly pay.
He worked 35 hours per week for 46 weeks in the year.
What is James' average pay per hour this year?
Give your answer to 2 dp.

Answers

Answer: £11.69

Explanation:

1) Work out 2% of £1600:
1600 x 2/100 =36

2) Add it on to the original number to get his new monthly pay:
1600 + 36 = £1636

3) Work out his yearly pay by:

a) finding the amount of months he worked:
46 / 4 = 11.5 months

b) Divide 11.5 into 2 bits and add them on:
1636 x 11 = 17997
1636 x 0.5 = 818

17997 + 818 = £18814

4) To get his pay per week:

18814 / 46 = £409

5) Finally, to get his pay per hour:

409 / 35 = 11.68671...
= £ 11.69

The perimeter of a square is represented by the expression 32x-12. . Write two equivalent expressions for the perimeter and explain how to find the length of one side. x=3

Answers

Answer:

P = 2(l+w) ----------(1)

P = 4l----------- (2)

P= 32x- 12

4l = 32x- 12

l = 8x- 3

One side will be equal to 21 units and the perimeter will be 84 units when x=3.

Step-by-step explanation:

The perimeter is given by the formula

P = 2(l+w) ----------(1)

where p= perimeter , l= length and w= width.

But a square has the length equal to the width so w= l and the formula becomes

P = 2( l+l)

P = 2 (2l)

P = 4l----------- (2)

The perimeter of the square is

P= 32x- 12

4l = 32x- 12

dividing the whole equation by 4 we get

l = 8x- 3

So the length of one side can be obtained by dividing the perimeter by 4.

If x= 3

then

l= 8(3)-3

l= 24- 3

l = 21

One side will be equal to 21 units and the perimeter will be 84 units.

P = 4l = 4(21)= 84

A sweatshirt manufacturer includes a shipping charge of $5.99 on all online orders. Customers also pay 2.5% tax on all their purchases. There is a linear equation between c, the cost of of the items purchased, and t, the total cost of including shipping and tax. Which statement is true about the function that represents the relationship between c and t. Brainly

Answers

Answer:

t = 1.025c + 5.99

Step-by-step explanation:

The shipping charge, = $5.99

Tax paid on purchases = 2.5%

Cost of item, c

Total cost, t, including shipping and tax

Total cost = Cost of item + tax on purchase +. Shipping fee

Tax on purchase : 2.5% * cost of item

Tax on purchase : 0.025c

Shipping = $5.99

General formula for a linear equation :

y = mx + c

Hence, for the cost model:

Total cost = Cost of item + tax on purchase +. Shipping fee

t = c + 0.025c + 5.99

t = 1.025c + 5.99

The graph

From the graph, we can see that:

The graph intersects with the x-axis at x = -4 and x = 8

So, we have

x = -4 and x = 8

Set the equations to 0

So, we have

x + 4 = 0 and x - 8 = 0

This means that the factors of the function represented by the graph are (x + 4) and (x - 8)

Find the tangent of the larger acute angle in a right triangle with side lengths 3, 4, and 5. Write your answer as a fraction

Answers

Answer:

4/3

Step-by-step explanation:

The larger accute angle in a 3 4 5 right triangle will always be the angle in between 3 and 5. Tangent theta = opposite side ÷ adjacent side, so 4/3.

The tangent should be in fraction is [tex]4\div 3[/tex]

Calculation of the tangent:

Since in a right triangle with side lengths 3, 4, and 5

Here there is the larger acute angle in the 3, 4 and 5 so it should be lies between 3 and 5

So, it should be like

= opposite side ÷ adjacent side
