Christine has $90 in a savings account. The interest rate is 5%, compounded annually. To the nearest cent, how much interest will she earn in 3 years?

$13.5

Step-by-step explanation:

90 x 5% = 4.5 x 3 = 13.5

b) well because you get well

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
