New allowance after it was decreased by 40%
= 100% - 40%
= 60%
Decrease in savings
= 40% x 35%
=
40100 x 35%
= 14%
New savings in percentage
= 35% - 14%
= 21%
21% of the original allowance = 63
1% of the original allowance = 63 ÷ 21 = 3
100% of the original allowance = 10 x 3 = 300
Tommy's original allowance = $300
Answer(s): $300
