Question

Barb had $112 in her savings account. Then deposited the same amount of money into her savings account in the next 4 months. Now she has $333 in her savings account. How much money,m, did Barb deposit each month?

Answer 1

• Subtract first: 333 - 112 = 221

• Divide second: 221 ÷ 4(months) = 55.25

• Equation: (333 - 112) ÷ 4

Barb deposited $55.25 each month. 

Hope this helps! :D

Answer 2

You don't mention interest, so I'll need to assume that interest calculations are not part of the picture here.  Barb now has $333; at the beginning she had $112.  That means that over four months she deposited $221. 

That comes to $221/4 per month, or $55.25.
