The ratio of the amount of money Jenny had to the amount of money Siti had was 3:4. The next day, their parent gave each of them some money. Siti received twice as much as Jenny. The ratio then became 5:8. If both girls had a total of $70 at first, how much did Siti receive?
J [][][] [][]
S [][][][] [][][][]
7 u --> $70
4 u --> 4/7 x 70 = $40
Siti received $40.
