Question

A student works part -time at an ice cream shop. She earns $200 a week plus 5% commision on sales over $1000 each week. Write a function f(x) for the student's earnings per week that are eligible for the 5% commission.

Answer 1

Explanation:

f(x) = x - 1000

describes how much earnings are eligible for the 5% commission.

g(x) = f(x)×0.05 = (x - 1000)×0.05

calculates how much the student would earn on commission.

h(x) = g(x) + 200 = (x - 1000)×0.05 + 200

calculates the total earning of the student per week.

x is always the sales per week.
