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
