Problema Solution
as part of the refreshments for Yvette's 25th birthday party, Kim plans to provide a bowl of M&M candies. She wants to mix custom printed M&Ms costing 60 cents per ounce with bulk M&Ms costing 25 cents per ounce to create 20lb of a mixture costing 32 cents per ounce. How much of each type of M&M should she use?
Answer provided by our tutors
let
x = pounds of custom printed M&M's
y = pounds of bulk M&Ms
60*x + 25*y = 32*20
x + y = 20
by solving this system we find
x = 4 pounds
y = 16 pounds
She should use 4 pounds of custom printed M&M's and 16 pounds of bulk M&Ms.
