Question

Please help me to solve this​

Answer 1

step-by-step explanation:

a)let the qty of the 2 mixtures be x and 3x

i.e;

x+3x=40 kg

4x=40kg

x=10kg

therefore the qty of 2 mixtures=  10kg and 30 kg

Answer 2

Answer:

If we'll mix 1 kg at $2.40 with 3 kg at $3.2 we get 4 kg at $x

1(2.4) + 3(3.2) = 4x

2.4 + 9.6 = 4x

12 = 4x

3 = x

The mixture is worth $3.00 per kg
