Answer 1

$45

Explanation:

Charles meets with customers on a daily basis. He uses the function f(x) = 5| x - 8| + 20 to calculate how many dollars he charges, per hour, for his time. How much does Charles charge per hour if a customer hires him for 3 hours?

f(x) = 5| x - 8| + 20

solve for when x = 3

f(3) = 5| 3 - 8| + 20

f(3) = 5| -5| + 20

f(3) = 25 + 20

f(3) = 45
