Answer 1

Explanation:

1) Regular price = $ 20

Reduction = 18% of regular price

= 0.18 * 20

= 3.6

Discount price = 20 - 3.6 = $ 16.4

2) Regular price = $ x

Reduction = 18% of regular price

= 0.18 * x

= 0.18x

Discount price =$ (20 - 0.18x)

3) Discount price = $ 18.45

Let the regular price be x

(100 - 18)% of x = 18.45

82% of x = 18.45

`(82)/(100)*x=18.45\\\\ x = 18.45* (100)/(82)\\\\ x = 22.50`

Regular price = $22.50
