The answer is B: 11.
To solve it, you need to solve the equation: 20.00=12.85+0.65x
First you need to multiply 36 *$30.22=$1087.92
This gives you the total amount paid
Then subtract 1087.92-900=187.92
This gives you the amount of money you paid in finance charges.
For the square root of a number to be a whole number, we would need to have a perfect square. 14 is given to us, so to find the missing number, all we have to do is square 14 (or multiply it by itself).
14 x 14 = 196
The missing number is 196.
Hope this helps! :)
