Mrs. Hasanah had $ 96.80. She spent $ 58.40 and gave the rest to her children. The elder child received twice as much as the younger child. How much did the younger child receive? *
→ 96.80 - 58.40 = 38.40
→ elder child's = 2 X younger child's
e = 2y
→ 38.40 = 2y + y
38.40 = 3y
12.80 = y
→ So, the younger child received $ 12.80
