Hey need to sell 1200+ more because if they want more than $3100 and they already have $700 they need $2400 and divide that by 2.
12 is the answer to this question
A^2+b^2=c^2 so c^2=12^2+16^2 which then simplifies to c^2=144+256 then simplify that to c^2=400. After that take the square root of c^2 and the square root of 400. So your answer is c=20
