An employee makes an hourly rate plus any tips they earn. This tip employee made a total of $400 by working 28 hours last week. If $253 of their total earnings was their tips, what is their hourly rate of pay?

Answer 1

Rate = $X per hour.

Pay = 28X + 253 = 400
28x = 400 - 253 = 147
X = $5.25 per hour.
