Question

Charmaine's Coffee shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Charmaine $5.75 per pound, and type B coffee costs $4.55 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $526.90. How many pounds of type A coffee were used?

Answer 1

Type A = $5.75 per pound
Type B = $4.55 per pound

1 set → 1 pound of Type A + 4 pounds of type B
1 set → 5.75 + 4(4.55)
1 set → $23.95

Number of sets = $526.90 ÷ 23.59 = 22

1 set → 1 pound of Type A
22 sets → 1 x 22 = 22 pounds of type A

Answer: 22 pounds of Type A
