Question

Please help me with this if you can, thanks!!

Answer 1

If Oliver made 10% more than he usually makes, he would not have $520 in his savings.

520 × 10% = 52

520 + 52 = 572

10% × 572 = 57.20

572 - 57.20 = 514.80

Oliver would have $57.20 saved. So, he would have $514.80 left to spend. Instead of adding 10% to his usual earnings, Oliver multiplied his earning by 10, falsely concluding that his spending money would be higher than what it actually is.
