(1)\tW and R collect stamps. If R gives W 15 stamps, he will have the same number of stamps as W. If W gives R 15 stamps, he will have ½ as many stamps as R. How many stamps does each of them have?

1st, draw the model for R having 2 small units (of 15 stamps each) more than W.

(2)\tIn April A,B C and D had a total of $324. In May , the savings of the 4 girls became equal when A’s savings was doubled, B’s savings was reduced by $4, C’s saving remained unchanged and D’s savings was increased by $9. What was B’s and D’s savings in April?

In May
A [ u ][u ]
B [ u ][u ] 4
C [ u ][u ]
D [u][u-9]

In Apr
u+2u+4+2u+2u-9=324


7u=329
u=47
B's in April=2*47+4=$98
D's in April=2*47-9=$87

Thank you, smartmummy!!!!
