Respuesta :

Answer:

Total cost = $105

Step-by-step 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.
