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

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

Step-by-step 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!!!

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
