Question

the owner of a natural foods store made 20 lb of a dried fruit and granola blend that is 50% dried fruit by mixing a dried fruit and granola blend that is 20% dried fruit with a blend that is 60% dried fruit. how many pounds of each type were used to get the desired blend?

Answer 1

see below

Explanation:

20 lb of a dried fruit and granola blend 50% dried fruit

mixing 20% dried fruit x lbs

60% dried fruit y lbs

x+y=20 so x=20-y

0.2x+0.6y =0.5*20 =10

0.2(20-y) +0.6y=10

4 -0.2y+0.6y =10

0.4y =6

y=15

x=5
