Question

Answer 1

Hi Vivian.

 

Since all of the ingredients are in $ per pound, we just need to do some multiplying and adding.

 

1 pound nuts * $13.50 per pound = $13.50

2 pounds of pretzels* $4.25 per pound = $8.50

4 pound of cheese crackers * $4.60 per pound = $18.40

 

Add the pounds 1 (nuts) + 2 (pretzels) + 4 (crackers) = 7 pounds of mix were made.

Add the cost of each:  $13.50 + $8.50 + $18.40 = $40.40 is the cost for all 7 pounds of ingredients.

 

If you need the price per pound, take our cost for the whole mix ($40.40) and divide it by the number of pounds (7) and you will have the price per pound.

 

$40.40/7 = $5.77 per pound.
