anonymous · Answer

So how would I set that up? Im kinda confused.

nottim · Answer

792=120($3.50x)+($7.50r) Maybe? i dunno

anonymous · Answer

Nope. Its not an answer

anonymous · Answer

Let x= the number of regular delivery package and y= number of  2days deliver package.
x + y = 120
3.5x + 7.5y = 792

anonymous · Answer

so 27?

anonymous · Answer

cause x = 27 and y = 93 when you solve that.
