## mskyeg 2 years ago A food store makes a 11–pound mixture of peanuts, almonds, and raisins. The cost of peanuts is $1.50 per pound, almonds cost$3.00 per pound, and raisins cost $1.50 per pound. The mixture calls for twice as many peanuts as almonds. The total cost of the mixture is$21.00. How much of each ingredient did the store use?

Possible answers: 3 lbs peanuts, 6 lbs almonds, 2 lbs raisins 8 lbs peanuts, 1 lb almonds, 2 lbs raisins 6 lbs peanuts, 3 lbs almonds, 2 lbs raisins 8 lbs peanuts, 2 lbs almonds, 1 lb raisins

since you have the possibilities, you can always cheat and check

3. satellite73

for example, is $$1.5\times 3+3\times 6+1.5\times 2=21 ?$$

im confused i though i needed an equation to do it that way that is my problem i cant figure out the equation.

p = peanuts a = almonds r = raisins pounds equation: p + a + r = 11 cost equation: 1.50p + 3.00a + 1.50r = 21.00 amount equation: a = 2p
