Devon babysits x hours a week after school for 5$ an hour, and also has a job as a cashier y hours a week for $10 an hour. He wants to earn atleast 70$. He can't work any more than 10 hours a week because of school.

x hours for babysitting

5$ an hour

= 5x

y hours for cashier

$10 an hour

= 10y

Earn atleast 70$

= 5x + 10y ≥ 70$

Can't work any more than 10 hours a week

= x + y < 10 hours

Inequality equation for the given statements is:

5x + 10y ≥ 70$ and x + y < 10 hours
