Question

Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision

Answer 1

He isn't correct. He spent 25% more time this week than the previous one.

Explanation:

We will make proportion.

first week 20 hours is 100%

second week 25 hours is x%

20 : 25 = 100 : x

When we multiply external and internal members we get:

20x =25 · 100 => x = 2500/20 = 125%

We conclude the following:

Evan spent 125% of the time in hours compared to the last week or Evan spent 25% more time this week than the previous one.

God with you!!!
