A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 40 kg if a mix that will sell for $1.30 per kg?

40kg

Step-by-step explanation:

x + y = 60, y = 60 - x

x(2.50) + y(1) = 60(1.50)

Substitute:

2.50 x + 60 - x = 90

1.50x = 30

x = 20 kg

y = 40 kg
