Ryan has $2,100 saved to pay for a car that costs $4,100. Ryan’s parents will loan him the remaining amount due for the car. They will charge him a simple annual interest rate of 4%. If Ryan takes 20 months to pay back the loan, what will be the amount he pays back on the loan?

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

The correct answer is c.
