Answer:
He is wrong.
Step-by-step explanation:
This indicates a percent increase in the amount of time he spends doing homework:
% increase = [tex]\frac{amount.of.increase.from.initial.amount.to.current}{initial.amount} * 100[/tex]
% increase = [tex]\frac{5}{20} * 100[/tex]
% increase = 25%
Meaning that he spent 100%+25% = 125% of the time he spent on homework last week.
Hence, he is wrong.
