Josh has $500 in his savings account. He deposits $25 into his savings account each month. He purchased home theater equipment f
zzz [600]

Answer:

  B. 10 months

Step-by-step explanation:

The balance on the loan will be ...

  b = 1600 - 80t . . . . . . where t is the number of months of payments

The balance in the savings account will be ...

  s = 500 + 25t

The savings account balance will be at least as much as the loan balance when ...

  s ≥ b

  500 +25t ≥ 1600 -80t . . . substitute the account balance expressions

  105t ≥ 1100 . . . . . . . . . . . . add 80t -500

  t ≥ 1100/105 ≈ 10.48 ≈ 10

It will take Josh 10 months to have enough savings to pay the loan in full.

_____

<em>Comment on rounding</em>

IMO, it makes no sense to round down, as Josh will NOT have enough in 10 months. He will have enough after he makes one more payment of $80. At 10 months, the loan balance is $50 more than the savings balance. It will be 11 months before there is enough savings to pay off the loan.
