Bartholomew and Maurice are buying school supplies. Bartholomew buys 5 notebooks and 6 binders for a total of $31.45. Maurice buys 4 notebooks and 8 binders for $38.60. Let n represent notebooks and b represent binders,what is the cost of a notebook?

Answers

Creating a system of equations, the cost of a notebook (n) will be: $1.25

n = note books.

b = binders.

Create a system of equation and solve for the variables.

Equation for school supplies bought by Bartholomew:

5n + 6b = 31.45 --> Eqn. 1

Equation for school supplies bought by Maurice:

4n + 8b = 38.60 --> Eqn. 2

Multiply Eqn. 2 by 6 and Eqn. 1 by 8.

40n + 48b = 251.6 --> Eqn. 1

24n + 48b = 231.6 --> Eqn. 2

Subtract Eqn. 1 from Eqn. 2.

16n = 20

Divide both sides by 16

n = 1.25

Therefore, creating a system of equations, the cost of a notebook (n) will be: $1.25

what the common denominators for 1/4 + 1/2

Answers

Answer:

The common denominator is 4

Step-by-step explanation:

To answer this question of what is [tex]\frac{1}{4} +\frac{1}{2}[/tex]

We first have to find the LCM(Least Common Multiple) of the unlike denominators 4 and 2 which is 4

So we multiply the numerator and denominator [tex]\frac{1}{2}[/tex] by 2 so we can add with the same denominator [tex]\frac{1*2}{2*2}=\frac{2}{4}[/tex]

[tex]\frac{1}{4} +\frac{2}{4}=\frac{3}{4}[/tex]

I put $300 into a back account that gives me 2.5% simple interest. How much interest do i earn after 3 years

Answers

Answer:

$23.07

Step-by-step explanation:

Present Value(PV) = $300

Interest rate(r) = 2.5 % or 0.025

Year(d) = 3 years

Find Future Value first.

This is the formula:

FV = PV(1 +r)[tex]^{d}[/tex]

Put the values to it.

FV = 300(1 + 0.025)[tex]^{3}[/tex]

FV = 300(1.025[tex])^{3}[/tex]

FV = 300(1.076890625)

FV = 323.0671875 or $323.07

The future value is $323.07. Now subtract it to the present value to get the interest.

323.07 - 300 = $23.07

The interest is $23.07
