Mr Tanaka used 10 gallons of gas. You find this answer by diving the denominator (3) with the total number of gallons of gas. So 15 divided by 3 is 5. Now you get the number 5, and multiply it by the numerator (2). 5*2 is 10. That is how you find the answer.
we know that
The simple interest formula is equal to

where
P is the Principal amount of money to be invested
I is the amount of money in interest
r is the rate of interest
t is Number of Time Periods
in this problem we have

substitute in the formula above and solve for P

![P=14.65/[(0.025)(2)]](https://tex.z-dn.net/?f=P%3D14.65%2F%5B%280.025%29%282%29%5D)

therefore
<u>the answer is</u>
