Question

How many pounds of cashews worth 7569

pounds of cashews worth 75C a pound must be mixed with 10 pounds of pecans worth
$1.50 a pound to make a mixture worth $1.00 a pound?

Answer 1

Let p = number of pounds of cashews

10 = number of pounds of pecans

p+10 = number of pounds of mixture

Value of cashews + Value of pecans = Value of mixture

0.75p + 1.50(10) = 1.00(p+10)

Multiply both sides by 100 to get 75p + 150(10) = 100(p+10)

The answer is (A).

Solving for p, we get:

75p + 1500 = 100p + 1000

-25p = -500

p = 20 pounds
