Answer:
8 hours
Step-by-step explanation:
You can solve this problem by inputting the values into an equation. Here is the equation below:
[tex]50 + 8x = 130[/tex]
Lets solve for x. First you subtract 50 from 130.
1) [tex]8x = 130 - 50[/tex]
2) [tex]8x = 80[/tex]
Next, you divide 80 by 8 to get x by itself.
1) [tex]x = \frac{80}{8}[/tex]
2) [tex]x = 10[/tex]
This means that you must mow lawns for 8 more hours to get a total of $130 in your bank account.
