Alisha has a $15,000 car loan with a 6 percent interest rate that is compounded annually. How much will she have paid at the end
lesantik [10]

I have another total loan payment formula (see attached):

Total = rate * principal * # of payments / (1-((1 + rate)^-n))

Total = .005 * 15,000 * 60 / (1- ((1.005)^-60)

Total = 4,500 / (1 -0.7413721962)

Total = 4,500 / 0.2586278038

Total = 17,399.52

I know that is NOT one of the answers but I am sure of the formula and the calculations.   I hope this helps.

Which expression is equivalent to:<br><br> 25a + 5b - 13
uysha [10]
25a + 5b - 13

5(5a + b) - 13 is your answer

using the distributive property, we can distribute 5 to all terms within the parenthesis:

5(5a + b) - 13 = 25a + 5b - 13


5(5a) = 25a
5(b) = 5b

25a + 5b - 13 = 25a + 5b - 13 (True)

hope this helps
