Answer:

Incorrect, he subtracted 10 (the amount spent) from 100 while he has to subtract the remaining amount to find the amount he spent meaning he has to subtract 90 from 100, not 10. The denominator is also wrong. The denominator would be 100, the original amount from which he wants to find the percentage. that would be

100-90/100

10/100

10%
