Asher had some blueberry cupcakes and strawberry cupcakes. He gave away 150 cupcakes to his cousin. 20% of them were blueberry cupcakes and the rest were strawberry cupcakes.

1. How many strawberry cupcakes did he give his cousin?
2. Asher gave some blueberry cupcakes to his brother. ⁵₇ of all the cupcakes he gave away to his cousin and his brother were blueberry cupcakes. How many blueberry cupcakes did he give his brother?

(a)
Percentage of strawberry cupcakes
= 100% - 20%
= 80%

Number of strawberry cupcakes that Asher gave to his cousin
= 80% x 150
= ⁸⁰₁₀₀ x 150
= 120 

(b)
Fraction of all the cupcakes he gave away to his cousin and his brother that were strawberry cupcakes
= 1 - ⁵₇
= ²₇

2 u = 120

1 u = 120 ÷ 2 = 60

Number of blueberry cupcakes that Asher gave to his cousin and his brother
= 5 u
= 5 x 60
= 300

Number of blueberry cupcakes that Asher gave to his cousin
= 150 - 120
= 30

Number of blueberry cupcakes that Asher gave to his brother
= 300 - 30
= 270

Answer(s): (a) 120; (b) 270
