6.2813

If you minus 27.31 of 23%. 23% would have to be changed into a decimal or whole number.
After that, you would want to check your answer on a calculator, which I usually do.
For the first picture using Pythagorean Theorem, we know that a^2 + b ^2 = c^2 but since we only know c ( 99.2) and b ( 62 ) we need to use the theorem to find a the equation we use for that is :
A = square root of ( c^2 - B^2 )
A = 77.44
Your question is vague. There is not enough information. How many balls are in the box? 15 boxes would cost 109.80 thought.
