Problema Solution
Kevin's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Kevin
$4.50
per pound, and type B coffee costs
$5.95
per pound. This month, Kevin made
116
pounds of the blend, for a total cost of
$617.70
. How many pounds of type B coffee did he use?
Answer provided by our tutors
let 'x' represent how many pounds of $4.50 coffee were used, then '116-x' represents how many pounds of $5.95 coffee were used.
617.70=4.50x + 5.95(116-x)
x=50
116-50=66
So Kevin should use 66 pounds of type B coffee ($5.95 per pound).
