Question

The owner of a local chocalate shop wants to develop a new trail mix. How many pounds of chocalate covered cashews worth $5.00 per pound should be mixed with 10 pounds of granola bites worth $3.00 per pound?

5x+3x=10
8x=10
------ = x=10/8 lbs.
8

Answer 1

Can't tell. I need to know the expected value of the mix, somewhere between $3 and $5 per lb.

If its cost is to be $n/lb, then

5x + 3*10 = n(x+10)
