Mark takes out a loan for $30000 to add on a new exam room for his practice. Now, the bank charges 5.4% interest.Question: how much interest will he pay in 5 years?=> 30 000 dollars = the money he owe=> 5.4 = 5.4% / 100% = .054Now, let's solve for the answer=> 30 000 dollars * 0.054 = 1 620 dollars. is the interest for 1 year.let's solve for 5 years.=> 1 620 dollars * 5 = 8 100 dollars'

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.
