1. sarah bought a television from a rental center. she makes 18 monthly payments of $93.27 with her credit card. the rental center charges $3.85 for every purchase made with a credit card. she also had to pay late fees in the amount of $41.50 nine different times. what is the total cost of the television?

We can split this all up into different parts then put it together at the end to make things easier.

Firstly, she makes those 18 monthly payments, so 93.27*18= $1678.86
Then, each one of those has a 3.85 surcharge for each one, so 3.85*18= $69.30
Finally, she has 9 lots of late fees, so 9*41.50 = $373.50

Now we can just add these together to get the total cost - 1678.86+69.30+373.50 = $2121.66

The correct answer is 10%
