Question

Joe’s Java Joint wants to sell a specialty holiday coffee blend that is a blend of their medium roast coffee which costs $8 per pound, and a flavored coffee which normally costs $16 per pound. If they want to sell the holiday blend for $20 for a 2-pound bag, how much flavored coffee should they use in each bag? Please provide an equation and show your work step by step.

Answer 1

$20 for a 2 pound bag = $10 for a one pound bag

16x + 8(2 - x) = 10(2)

8x = 4

x = 0.5

Use 0.5 pound of flavored coffee and 1.5 lb of roast coffee
