Question

Mike is on vacation and decides to rent a bike for part of the week. The rental cost is represented by the function c(d) = 25+20d, where is the number of days of use and c(d) is the total cost for d days of use. How much does the bike cost Mike if he uses it for 4 days?

Answer 1

Cost for 4 days is 105

Explanation:

To get the cost for 4 days, we simply substitute 4 for the value of d in the equation

Thus, we have

c(4) = 25 + 4(20)

C(4) = 25 + 80

C(4) = 105
