Let’s set up an equation:

You start with 25 dollars, you make 7 an hour:

7x + 25

Set this to 165:

7x + 25 = 165

Now subtract 25 from both sides:

7x = 140

Divide both sides by 7:

x = 20

So, you must babysit 20 hours.

Hope this helps!

Make an equation:
25 + 7h = 165

h is the total number of hours you spend babysitting.

Solve for h to find how many hours you need to babysit to have a total of $165 in your bank account.

25 + 7h = 165
Subtract 25 from both sides.

7h = 140
Divide both sides by 7.

h = 20

You must spend 20 hours babysitting to have $165 in your bank account.
