To solve the problem we must establish two equations.
let x be the mass of the 20 cents almonds
y be the mass of the 36 cents mixture
first equation is:
x + 40 = y
the second equation is:
0.2x + 40(0.4) = 0.36y
solving the equations simultaneously
x = 10 lb of the 20 cents almonds is needed to mix
Answer:
D
Step-by-step explanation:
3/4 × 2/6 = 1/4
3/4÷6/2=1/4
1 3× (6- 3) = 39
1 4× (6-3) = 42
1 6× (6-3) = 48
1 6 × (6-3) = 48
Both C and D are the greatest.
