Answer:
4 boxes
Step-by-step explanation:
Given
Represent Dark Chocolate with D and Milk Chocolate with M
[tex]D = 24[/tex] pieces
[tex]M = 20[/tex] pieces
[tex]Total = 169[/tex]
First, we need to determine the quantities in e boxes of dark chocolate.
[tex]Quantity = 24 * 3[/tex]
[tex]Quantity = 72[/tex]
Subtract this quantity from the total; This gives the quantities of milk chocolate
[tex]Milk\ Chocolate = 169 - 72[/tex]
[tex]Milk\ Chocolate = 97[/tex] pieces
Lastly, divide this by the 20 pieces (of milk chocolate) to get the number of boxes.
[tex]Boxes = 97/20[/tex]
[tex]Boxes = 4.85[/tex]
Since, we're getting the fewer boxes, we have to round down
[tex]Boxes = 4[/tex]
