³₅ of Asher's savings comprised of 20-cent coins and 50-cent coins. Asher used some 20-cent coins to purchase a yoyo. The number of 50-cent coins left was 40% more than the number of 20-cent coins left. Given that Asher had 40 more 50-cent coins than 20-cent coins left in the end, find the amount of money Asher spent on the yoyo.

	20-cent coins	50-cent coins
Before	3x7 = 21 u	2x7 = 14 u
Change	- 11 u
After	5x2 = 10 u	7x2 = 14 u

Fraction of Asher's savings that comprised of 50-cent coins
= 1 - ³₅
= ²₅

Number of 50-cents coins in the end in percentage
= 100% + 40%
= 140%

140% = ¹⁴⁰₁₀₀ = ⁷₅

Number of 50-cent coins remains unchanged. Make the number of 50-cent coins the same.  LCM of 2 and 7 is 14.

Number of more 50-cent coins than 20-cent coins
= 14 u - 10 u
= 4 u

4 u = 40

1 u = 40 ÷ 4 = 10

Number of 20-cent coins spent on the yoyo 
= 21 u - 10 u
= 11 u
= 11 x 10
= 110

Amount that Asher spent on the yoyo 
= 110 x 0.2
= $22

Answer(s): $22
