Claudia is going to buy a used car for $9,500. She can finance it at the car dealership at 11% interest for 3 years, or she can finance it at the bank at 7% interest for 6 years. What is the difference in interest cost between the car dealer loan and the bank loan? If she takes the loan from the car dealership, Claudia will have to repay $ less in interest than if she took the loan from the bank.

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
