Question

Jaxon is studying for a test. He has studied for the following number of minutes each day this week. How many minutes does Jaxon need to study on Thursday to bring his five-day average to 50 minutes?

Answer 1

Explanation:

Let x be the study time Thursday:

5 day average
`=(70+45+0+40+x)/(5)`

`=(155+x)/(5)`

For the average to be 50 minutes:

`50=(155+x)/(5)`

`250=155+x`

`x=95`

Solution: Jaxon needs to study for 95 minutes Thursday.
