Sam will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $53 and costs an additional $0.14 per mile driven. The second plan has an initial fee of $40 and costs an additional $0.16 per mile driven.

Step-by-step explanation:

Let's set up two equations:

The first plan has an initial fee of $53 and costs an additional $0.14 per mile driven.

The First Plan:

y = .14x + 53

Where y is the total cost and x is the number of miles driven

The second plan has an initial fee of $40 and costs an additional $0.16 per mile driven.

The Second Plan:

y = .16x + 40

Where y is the total cost and x is the number of miles driven

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
