Ashley and a friend have dinner at Red Lobster. Ashley’s meal costs $15.85 and she leaves an 18% tip. Her friend’s meal costs $1
FinnZ [79.3K]

Answer: Ashley spent $18.70 and the friend spent $17.16

Step-by-step explanation:

Original cost of Ashley's meal = $ 15.85

tip left = 18% of 15.85

that is

tip left = 0.18 x 15.85 = $2.85

All together, Ashley will pay

$15.85 + $2.85

= $18.70

The friend's original cost = $14.30

tip = 20% of 14.30

= 0.20 x 14.30

= $2.86

All together , the friend will pay

$14.30 + $2.86

=$17.16

Therefore:

Ashley spent $18.70 and the friend spent $17.16
