1. Joanne and Bob were given the same amount

of allowance last month. After Joanne spent $18

and Bob spent $3, the amount of allowance Bob

had left was 6 times that of what Joanne had left. How

much allowance did each child receive last month?

2. Kivesh, Dave and Fred have a total savings of

$2712. Dave's savings is twice that of Kivesh's.

Fred's savings is thrice that of Kivesh's. How much

Q1)
They had same amount last month.
After spending,

1 unit + $18 = 6units + $3
5 units -----> $18 - $3 = $15
1unit -------> $15 / $3 = $5
Joanne ----> $5 + $18 = $23 (answer)

Q2)
Dave ----> 2units
Kivesh --> 1 unit
Fred -----> 3 units

(2 + 1 + 3)units ------> $2712
6 units ------->$2712
1 units -------> $2712 / 6 =$452
Difference between Fred & Kivesh ---> 3 units - 1unit = 2 units
2 units -------> 2 x $452 = $904 (answer)
