100% + 50% = 150%

Selling price of the dress
= 100% of the price of the dress + 50% of the price of the dress
= 2 u + 1 u
= 3 u
Selling price of the blouse
= 100% of the price of the blouse + 60% of the price of the blouse
= 5 p + 3 p
= 8 p
Price of the second dress after 25% discount in percentage
= 100% - 25%
= 75%
Price of the second dress after 25% discount in units
= 75% x 3 u
=
75100 x 3 u
= 2.25 u
Profit made for the second dress in units
= 2.25 u - 2 u
= 0.25 u
0.25 u = 36.75 - 33 = 3.75
1 u = 3.75 ÷ 0.25 = 15
1 u + 3 p = 33
1 x 15 + 3 p = 33
15 + 3 p = 33
3 p
= 33 - 15
= $18
Profit made on the blouse = $18
(b)
1 p = 18 ÷ 3 = 6
Selling price of the blouse
= 8 p
= 8 x 6
= $48
Answer(s): (a) $18; (b) $48
