Question

The price of a fan is $15. This price is 27% lower than last week.

What was the price of the fan last week?

Answer 1

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

Answer 2

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
