The Chocolate Factory has to package 60 pounds of chocolate.

Each box must contain 3/4 pound of chocolate.
Each box is then sold for $3.50.
If all of the boxes are sold, how much will the Chocolate Factory collect?

(60 * .75) * 3.50 = ?

To calculate how much the Chocolate Factory will collect, we need to find out how many boxes they will need to package and then multiply that number by the selling price of each box.

First, we need to find out how many boxes are required to package 60 pounds of chocolate. To do that, we divide the total weight of chocolate by the weight of each box:
60 pounds ÷ (3/4 pound per box) = 60 ÷ (3/4) = 60 × (4/3) = 240/3 = 80 boxes

So, the Chocolate Factory will need to package 80 boxes.

Next, we multiply the number of boxes by the selling price per box to find out how much the Chocolate Factory will collect:
80 boxes × $3.50 per box = 80 × $3.50 = $280

Therefore, if all of the boxes are sold, the Chocolate Factory will collect $280.
