Answer: If the 40% off coupon is used, the subtotal will be $12.69

The gratuity would be exactly $4.23 (He will probably leave $4.25)

Step-by-step explanation: To find out the amount of the discount

.40 × 21.15 = 8.46

To find the new subtotal, subtract 12.15 - 8.46 = 12.69

To figure the tip: .20 × 21.15 = 4.23

Changing the percent to a decimal means divide the 20 by 100.
