Ali's earnings vary directly with the number of hours he works. Suppose that he worked 10 hours yesterday and earned $130. how much will he earn today is he works 13 hours?

Answer: He earns $169 after 13 hours

Step-by-step explanation:

To solve this we need to find out how much he earns per hour.

This can be identified using simply division.

130/10=13

He earns $13 per hour.

Now we multiply 13*13=169

He earns $169 after 13 hours

He would earn $169 because if he earns $130 in 10 hours that means he earns $13 per hour. You have to multiply 13 X 13 to see his earnings in 13 hours.
