We know that Jason has three <em>more</em> than four <em>times</em> the amount of money Jeff has. So:

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

Combine like terms:

Subtract 3 from both sides:

Divide both sides by 5:

So, Jeff has $13.80
We know that Jason has three more than four times the amount of money Jeff has.
Therefore, Jason has:

Multiply and add:

So, Jason has $58.20 and Jeff has $13.80.
And we're done!
