When Cat sold her car for $14,000, she put all of the money into a savings account. If the account earns 3.9% interest, how many YEARS will it take her to earn $1365 in interest?

Roughly 7.35169 years

Step-by-step explanation:

So we want an increase of money of $1365

So our target value is 15,365

Let's model the expression: target = initial_value * (1.39)^y, where y is years

This should immediately spark logarithms into your head

Use change of base formula:

y = 7.35169 years

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
