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 + 20 d c(d)=25+20d , where d is the number of days of use and c ( d ) 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? $120

Answer 1

Total cost = $105

Explanation:

The rental cost is represented by the function c(d)=25 + 20 d.

We need to find the cost of the bike if he uses the bike for 4 days.

Put d = 4 in the given expression.

c(4)=25 + 20 (4)

=25+80

=$105

So, the cost of the bike for 4 days is $105.
