At The Nut House, a pound of cashews sells for $6.00/lb and a pound of peanuts sells for $3.00/lb. If you would like to make a 3 pound mixture of peanuts and cashews at a cost of $3.75 per pound, how many pounds of cashews must you use?

LEt Cashews in the mixture be C lb therfore peanuts will be 3-c.
The equation will become
6c + 3(3-c) = 3 * 3.75
3c + 9 = 11.25
3c = 2.25
c = 2.25/3
c = 0.75
thersfore there will be 0.75 lb of ceshew
