Kelko will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $57 and cost an additional $0.08 per mile driven. The second plan has an initial fee of $50 and costs and additional $0.10 per mile driven.
Questions (contd)
(a) For what amount of driving do the two plans cost the same?
(b) What is the cost when the two plans cost the same?
Answer:
(a) 100 miles
(b) $65
Step-by-step explanation:
Given
Plan 1:
[tex]Initial\ Fee = \$57[/tex]
[tex]Additional = \$0.08[/tex] per mile
Plan 2:
[tex]Initial\ Fee = \$50[/tex]
[tex]Additional = \$0.10[/tex] per mile
Solving (a): Number of miles when both plans are equal
Represent the distance with x and the cost with y
So:
Plan 1:
[tex]y = 57 + 0.08 * x[/tex]
Plan 2:
[tex]y = 50 + 0.10 * x[/tex]
To solve (a), we equate both plans together; i.e.
[tex]y = y[/tex]
[tex]57 + 0.08x = 50 + 0.10x[/tex]
Collect Like Terms
[tex]0.08x - 0.10x= 50 - 57[/tex]
[tex]-0.02x= -2[/tex]
Solve for x
[tex]x = -2/-0.02[/tex]
[tex]x = 100[/tex]
Hence, 100 mile would cost both plans the same
Solving (b): Cost when both plans are the same:
In this case, we simply substitute 100 for x in any of the y equation.
[tex]y = 57 + 0.08 * x[/tex]
[tex]y = 57 + 0.08 * 100[/tex]
[tex]y = 57 + 8[/tex]
[tex]y = 65[/tex]
Hence, the amount is $65

Find the slope of the line described by 28x −12y + 50 = 0.
Step-by-step explanation:
Move 12y to the other side
12y=28x + 50
Divide both sides by 12
y=7x/3 + 25/6
Slope is 7/3
-x + y = 2
3х – 5у = -4

Sasha's mom is ordering food trays for Sasha's elementary school graduation party. Banquet Brothers sell a tray with 48 servings of pasta for $60. Cookin' Catering sells a tray with 30 servings of pasta for $72. Which company has the better deal?
Answer: Banquet Brothers has better deal.
Step-by-step explanation:
Given: Banquet Brothers sell a tray with 48 servings of pasta for $60.
Cost per serving = [tex]\$\dfrac{60}{48}=\$\dfrac{5}{4}=\$\ 1.25[/tex]
Cookin' Catering sells a tray with 30 servings of pasta for $72.
Cost per serving = [tex]\$\dfrac{72}{30}=\$\ 2.4[/tex]
Since, Cost per serving in Banquet Brothers < Cost per serving in Cookin' Catering
So, Banquet Brothers has better deal.

Use the following function rule to find f(2).
Answer:
f(2)=-7-7|2|
=-7-14
=-21
Step-by-step explanation:
The x in f(x) is replace with 2,so example:
f(x) =3+4(x)
Find f(4),
f(4)=3+4(4)
=3+16
=19
The value of f(2) is -19 for f(x)=-7-7|x|
What is a function?A relation is a function if it has only One y-value for each x-value.
Given function is f(x)=-7-7|x|
f of x equal to minus seven minus seven times of mod x
f(x)=-7-7|x|
Now to find the value of f(2) we have to replace x value with 2
f(2)=-7-7|2|
f(2)=-7-12
f of two equal to minus seven minus twelve
f(2)=-19
f of two equal to minus nineteen.
Hence, the value of f(2) is -19 for f(x)=-7-7|x|

The graph shows the relationship between the number of strawberries eaten and the approximate number of calories consumed. Which statement is true?
Each strawberry contains 4 calories.
Each strawberry contains 3 calories.
Twenty-four strawberries contain 6 calories.
Four strawberries contain 15 calories.
9514 1404 393
Answer:
Each strawberry contains 4 calories
Step-by-step explanation:
The graph crosses the vertical line for 1 strawberry above the intersection with the horizontal line for 3, so there are more than 3 calories in 1 strawberry. The graph crosses "strawberries = 1" at about "calories = 4", matching the first statement.
Similarly, the graph crosses the vertical line for 4 strawberries above the horizontal line for 15 calories. An estimate of 16 calories for 4 strawberries is consistent with the first statement (4 calories in each strawberry).
The point (6, 24) is on the graph, but it means (6 strawberries, 24 calories), not the other way around.
The appropriate choice is ...
Each strawberry contains 4 calories
Answer:
its 4 calories, A
