Chang and carlotta solve this problem in two different ways. you have $50 $ 50 in your bank account. you make $8 $ 8 per hour mowing lawns. how many hours must you mow lawns to have a total of $130 $ 130 in your account? use the drop-down menus to complete the sentences below.

10 hours

Step by step: if you make 8$ an hour, that means you multiply 8 times how many hours you work and it will tell you how much you will make in that many hours. So we need to find out how many hours it will take to get 80$ because we already have 50$ and we need 130$. 130$ (what we need) - 50$ (what we have) is 80$. So we need to find out how many hours we must work to get 80$. Now, we know that we make 8$ an hour, so 8 times the hours must equal 80. So let’s set up the equation. h will stand for our unknown hours and we will solve for h. Problem: 8*h=80. So to get h by itself we dive both sides by 8. 8h/8= h, and 80/8=10. So now our problem is: h=10. This is our answer, hours = 10 so it would take 10 hours of working to have 130$ in your bank account. Hope this helps!
