You have $25 in your bank account. You make $7 per hour babysitting. How many hours must you babysit to have a total of $165 in
your account?

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.
