PLEASE HELP ME PLEASEE

Richard and Davina ate dinner at a restaurant together. Davina had a coupon for 25% off their meal. They both agree that they should leave a 20% tip on their meal. However, Richard believes they should calculate the tip before taking into account the coupon, and Davina believes they should calculate the tip after taking into account the coupon. If their meal costs $48.80 before using the coupon, by how much will the tip increase if they use Richard's method instead of Davina's method?

Answer: tip would increase by $2.44

Step-by-step explanation:By applying Richard's method: tip given= 20% of 48.8

Tip given=$9.76

Now applying Davina's method: cost need to be paid after taking coupon into an account= 48-25%48.8= $36.6

Tip given =20% of 36.6=$7.32

Amount of tip given increased= $9.76-$7.32=$2.44

The tip would increase by $0.44. If you find how much the tip would be originally and compare it to the tip after the coupon is used, it would be $9.76 - $9.32 = $0.44. Richards method would give an extra $0.44 as a tip.
