caramels costing 1.75 per pound, are mixed with cream chocolate costing 2 per 
pound to make a 5 pound mixture that will be sold at 1.90 per pound..
how many pounds of each are needed?
:
Let x = amt of stuff costing $2 a lb
then
(5-x) = amt of stuff costing $1.75 a lb
:
2x + 1.75(5-x) = 1.90(5)
solve for x
