Ermaine’s father owes $6,300 in interest at the end of a 60-month car loan at a 7% simple annual interest rate. what was the original loan amount?

The pertinent formula is i = p*r*t.  Here, i = $6,300, r = 0.07 and t = 5 yrs.

We want to solve this for the principal, p.  Since i = p*r*t,  p = i / (rt).  In this case, the principal was:

p = $6,300 / [0.07*5] = $6,300 / 0.35 = $18,000

the answer is 21%.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
