New allowance after it was increased by 35%
= 100% + 35%
= 135%
Increase in savings
= 35% x 20%
=
35100 x 20%
= 7%
New savings in percentage
= 20% + 7%
= 27%
27% of the original allowance = 189
1% of the original allowance = 189 ÷ 27 = 7
100% of the original allowance = 100 x 7 = 700
Eric's original allowance = $700
Answer(s): $700
