Andrea bought some clothing on a department store credit card. Her total came to $250. She qualified for interest-free financing. She made a first payment of $35 and agreed to pay $25 twice a month until the $250 balance was paid. How long will it take for Andrea to pay off her bill? Show your work.

A little over 4 months.

Step-by-step explanation:

First, we subtract the first payment she made from the total.

250 - 35 = 215

Now we have $215 left to pay off. She pays $25 off twice a month, so that's $50 a month.

215 ÷ 50 = 4 months, with a remainder of $15 to pay off.

Andrea will have paid it off 5 months later, or 4.5 months since she's paying twice a month, however, assuming this is an answer requiring work and is not multiple choice, my final answer would be a little over 4 months.

the discriminant is 64 + 4*1*12 = 112

this is prime.

9 x 8 divided by (5-3)=36
