a= 4,368
b= Is an estimate. I estimate around 4,000 (80 x 50)
c= *I don't completely understand what that means*
a= 38,037
b=I would estimate about 36,000 (400 x 90)
c= *I don't understand what this question means* (It's been to long since I have done this kind of math)
Hint* Get a TI-84 PLUS CE calculator. It's expensive but you might need it for more advanced math like graphing and advanced equations.
