Answer:
Explanation:
Follow these steps. First let's look at the problem:

Multiply each side by j/1:

which simplifies to

Now take the natural log of both sides:

The power rule says that we can bring the exponent down in front of the natural log:
(j) ln(1.04) = ln(2) and then divide both sides by ln(1.04)
Do the division on your calculator to get that j = 17.7
