Wendy had some caramel apples. She sold 20% of her caramel apples and gave half of the remainder to her cousin. After that, she bought 50 caramel apples and had a total of 70 caramel apples in the end. How many caramel apples did Wendy have at first?
Percentage of caramel apples that Wendy left after selling 205 of her caramel apples
= 100% - 20%
= 80%

Fraction of caramel apples that Wendy had left after giving to her cousin
= ¹₂ x 80%
= ²₅

Number of caramel apples that Wendy had left = 2 u

Number of caramel apples that Wendy had in the end = 2 u + 50

2 u + 50 = 70
2 u = 70 - 50
2 u = 20

1 u = 20 ÷ 2 = 10

Total number of caramel apples that Wendy had at first
= 5 u
= 5 x 10
= 50

Answer(s): 50
