Nathan’s Boy Scout troop is making M&M and peanut trail mix for a future hike. The M&M’s cost $3 per pound and the peanuts cost $2 per pound. The Boy Scouts spend $74 to make 30 pounds of trail mix. How many pounds of M&M’s did they buy?

Answer :

Answer:

14 lbs of M&M's

Step-by-step explanation:

x - pounds of the M&M's;

y - pounds of the peanuts

x + y = 30

3 x + 2 y = 74

y = 30 - x

3 x + 2 ( 30 - x ) = 74

3 x + 60 - 2 x = 74

x = 74 - 60

x = 14
