The cost in dollars, c, of renting a carpet cleaner is given by the linear equation

c = 20 + 25x, where x is the number of days.

use this model to find the number of days it can be used for $170.
a) 4
b) 5
c) 6
d)

C) 6

Step-by-step explanation:

Given : The cost in dollars, C, of renting a carpet cleaner is given by the linear equation  , where x is the number of days.

To find the number of days it can be used for $170, we put C= 175 in the equation, we get

Hence, the required number of days = 6.
