Evan gets a loan of $3,000 for a car. the interest rate on the loan is 7.5% annually. if he pays the loan off in two years, how many dollars in interest will he pay?

After the seventh month of a 12-month loan: the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = , and the denominator is: {(n) + (n + 1) + + (n + 11)} = . therefore, the fraction is numerator/denominator (to the nearest tenth) = %
