Answer asap; a bank customer has $172 in a bank account. she withdraws $85 per month for the next 3 months. she also writes 4 checks for $45.75 each. how much money should she deposit to ensure that her balance is at least $25 at the end of the 3 months?

answer: if she has $172 and has no more money coming in, i believe the answer would be $291.

step-by-step explanation:   if she takes out $85 for 3 month that's a total of $255. the 4 checks equal to $183. she spent a total of 438.

so 172 (what she had) - 438 (what she spent) = -266. in order to bring her balance to $0 she needs to deposit $266 into her account. she needs at least $25. so, add 25 to 266 and you get $291.
