Answer:
4 months
Explanation:
Let the number of months that they deposit into their accounts be m.
Grace has $81 in her bank account and deposits $68 per month into her account. This means that after m months, she will have:
81 + 68m
Jasmine has $53 and deposits $75 per month into her account. This means that after m months, she will have:
53 + 75m
To find the number of months it will take for them to have the same amount, we equate the amount that they each have:
81 + 68m = 53 + 75m
Collect like terms and simplify:
81 - 53 = 75m - 68m
28 = 7m
=> m = 28 / 7 = 4
It will take 4 months for them to have the same amount.
