How many pounds of candy that sells for $0.78 per pound must be mixed with candy that sells for $1.33 per pound to obtain 8 pounds of a mixture that should sell for $0.98 per pound

Step-by-step explanation:

Let x and y pounds of Candy A and Candy B be mixed respectively.

Rate of Candy A and Candy B are $0.78 and $1.33 per pound respectively.

Now,

(A) x + y = 8

(B) 0.78x + 1.33y = 7.84

Solving both equations :

0.33y = 1.6

x = 3.16 pounds of Candy A

y = 4.84 pounds of Candy B

(3x-8) or (3x+8)

step-by-step explanation:

b. b < 1 might be the correct answer
