The total cost c (in dollars) to participate in a ski club is given by the literal equation c=85x+60, where x is the number of ski trips you take.
a. solve the equation for x.
b. how many ski trips do you take if you spend a total of $315? $485?

a.

b. 3 and 5 ski trips

Step-by-step explanation:

Given function that shows the total cost for the x trips,

a. For solving the above equation for x,

We need to isolate x on the left side of the equation,

From equation (1)

b. If C = $ 315,

= 3,

If C = $ 485,

= 5

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
