Question

Evan has $1,000 in a bank account that will earn 4% interest each year. Kinney has $1,000 in an account that will earn 7% each year. After how many years will Kinney have made twice as much interest as Evan?

Answer 1

2*1000*(1+0.04)^t = 1000*(1+0.07)^t

2*1.04^t = 1.07^t

2=(1.07/1.04)^t

1.0288^t = 2

t = log(2) / log(1.0288) = 24.4

So it takes more than 24 years. the interest is compounded every year, so need powered by t.

Answer 2

1000(1 + 0.07)t = 2[1000(1 + 0.04)t]

Can yo solve for t and answer?
