Given : The cost in dollars, C, of renting a carpet cleaner is given by the linear equation [tex]C = 20 + 25x[/tex], 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

[tex]175 = 20 + 25x\\\\\Rightarrow\ 25x=170-20\\\\\Rightarrow\ 25x=150\\\\\Rightarrow\ x=\dfrac{150}{25}=6[/tex]

Hence, the required number of days = 6.
