Question

The cost of renting a chain saw is $3.75 per hour plus $7.50 for

a can of gas which is modeled by f(h) = 3.75h + 7.50. Find the
cost of using the chain saw for 4.5 hours.

Answer 1

$24.38

Explanation:

f(h) = 3.75h + 7.50

h = 4.5

f(4.5) = 3.75(4.5) + 7.50

f(4.5) = 24.375

Answer: $24.38
