    Answer:

    (a)\ c(x) = 39 + 0.09 x

    (b)\ \$53.4

    Step-by-step explanation:

    Given

    Base\ Charge = \$39

    Rate = 0.09 per mile

    Solving (a): Linear Equation

    The total charges (c(x)) is: the base charge + the rate * number of miles (x).

    So, we have:

    c(x)= 39 + 0.09 * x

    c(x) = 39 + 0.09 x

    Solving (b): Cost of rent, if miles = 160

    This implies that x = 160

    So, we have:

    c(x) = 39 + 0.09 x

    c(160) = 39 + 0.09 *160

    c(160) = 39 + 14.4

    c(160) = 53.4
