Answer:

A. between $46.75 and $85.00

B. between $57.04 and $103.70

Explanation:

You want the discounted price and final cost of a meal that has an original cost between $55 and $100 before a 15% off coupon is applied and a 22% tip is added to the reduced cost.

A. Discounted price

The price of the meal after the 15% coupon is used will be in the range ...

  • $55 · 0.85 = $46.75
  • $100 · 0.85 = $85.00

B. With tip

The final cost after adding the tip will be in the range ...

  • $46.75 · 1.22 ≈ $57.04
  • $85.00 · 1.22 = $103.70

The final cost of the meal will be between $57.04 and $103.70.
