Question

13) The linear equation in two variables y = 0.10x +175 models the total weekly cost, y, in

dollars, for renting and driving it x miles. The equation indicates that the rental
company charges a fixed amount of $175 for the week plus a cost of $0.10 for each mile
the car is driven. Find the solution of y = 0.10x +175 using 185 for x.

Answer 1

To find the solution of y = 0.10x + 175 using 185 for x, we simply need to substitute x = 185 into the equation and solve for y:

y = 0.10(185) + 175

y = 18.5 + 175

y = 193.5

Therefore, if you rent and drive the car for 185 miles in a week, the total weekly cost will be $193.50.
