Answer:
Step-by-step explanation:
Their original bill was $135.65. If they wanted to leave a 20% tip on the original bill amount, then the amount of tip that they would leave is
20/100 × 135.65 = 0.2 × 135.65 = $27.13
They had a 15% off coupon on meals more than $75. This means that their meal qualified for the coupon. The amount discounted would be
15/100 × 135.65 = 0.15 × 135.65 = 20.3475
The total for the bill with the discount and tip included would be
135.65 - 20.3475 + 27.13 = $142.4325
