Panchito has 10% cranberry juice and also a 20% apple juice how much of each should he mix to obtain 100 fluid ounces of a 16% cranberry apple juice blend?

Question

What is the setup? Word problems always stump me also the answers please I already got them but I need to double check

Answer 1

x = unknown amount of cranberry juice

y = unknown amount of apple juice

Create a system

x+y = 100 (for quantity of juice)

.10*x+.20*y = 100 * .16

Then solve
