Answer:
$20.55
Step-by-step explanation:
(price last week) - 27% × (price last week) = $15 . . . . what the problem says
(price last week) × (1 - 0.27) = $15 . . . . factor out price
(price last week) = $15/0.73 . . . . . . . . . divide by the coefficient of price
(price last week) ≈ $20.55

x=price last week, 27% less is 0.27. Since it is 27% less than 100%, that is 100%-27%=73%, which is 0.73
0.73x=price now=$15
divide by 0.73 both sides
15/0.73=$20.55 price last week ANSWER
