Question

Alyssa got a job as a part-time waitress at a diner. She earns a daily wage of $50 and a 20% tip from the bill amount of the customers she serves. Which equation represents Alyssa’s total daily earnings (y) based on the total bill amount of the customers she serves (x)?

y = 0.7x – 20

Answer 1

y = 0.2x + 50
when you convert a percent to a decimal you move it two points to the left then add the 50 for daily earnings
