Answer:
(C) 9
Step by step:
11-2=9 and it’s asking for both p and q combined so no need to worry about that
She spent $310 on the singing camp.
MY WORK:
I multiplied $86.50*20 because $86.50 is the amount she deposited for 20 months. $86.50*20=$1740.00
Then I multiplied $24.50*20 because she spent $24.50 for 20 months. $24.50*20= $490.00
Then I subtracted $1740.00-$490.00 because she spent $490 out of her bank account. $1740.00-$490.00=$1240.00
Finally, because its 1/4 of her money, I divided $1240.00 by 4. $1240 divided by 4= $310
Hope this helps!!

This is what I found in a calculator
let <ACB=<C,
Here h=26 due to opposite to right angle is hypotenuse and b=10 Is a base and p=24 due to opposite to the angle <C
so,
Cos<C=b/h
=10/26
=5/13
