Answer:
8 hours
Step-by-step explanation:
You can solve this problem by inputting the values into an equation. Here is the equation below:

Lets solve for x. First you subtract 50 from 130.
1) 
2) 
Next, you divide 80 by 8 to get x by itself.
1) 
2) 
This means that you must mow lawns for 8 more hours to get a total of $130 in your bank account.
225*(x+1/25)+225*(y-4/9)=225*1
9(x+1)+25(y-4)=225
9x+9+25y-100=225
9x-91+25y=225
9x=225+91-25y
9x=316-25y
x=316/9-25/9
