Question

A delivery driver makes $78 each day that she works and makes approximately $7 in tips for each delivery that she makes. If she wants to make at least $225 in one

day, at least how many deliveries does she need to make?

Answer 1

ANSWER: 21 deliveries.

EXPLANATION: For this problem, we would use the equation 78 + 7x = 225. 78 is the flat rate she gets for going out and making deliveries, 7 is each tip she gets per delivery, and x = number of deliveries. To break down this equation, solve algebraic wise. 78 + 7x = 225. 7x = 147. x = 21. She would need to make at least 21 deliveries to make $225 in one day.
