Answer:
Randall earned $33.75 from selling baseball cards.
Step-by-step explanation:
Given:
Cost for each pack of card = $3.75
Number of packs = 3
Hence Cost of 3 packs of card can be calculated by multiplying Cost for each pack of card with number of packs
Cost of 3 packs of card = ![\$3.75\times3=\$11.25](https://tex.z-dn.net/?f=%5C%243.75%5Ctimes3%3D%5C%2411.25)
Also Given:
Each pack contains = 12 cards
3 pack contains = number of cards in 3 pack
By using Unitary method we get;
Number of Card in 3 pack = ![12\times3=36 cards](https://tex.z-dn.net/?f=12%5Ctimes3%3D36%20cards)
Hence Purchasing Price of 36 cards = $11.25
Now Given that;
Selling price for each cards = $1.25
Selling price for 36 cards = price for 36 cards
By Using Unitary method we get;
Selling price for 36 cards = ![\$1.25\times 36 = \$45](https://tex.z-dn.net/?f=%5C%241.25%5Ctimes%2036%20%3D%20%5C%2445)
Now Money Earned can be calculated by subtracting Purchasing Price with selling price we get;
Total Money earned = ![45-11.25 = \$33.75](https://tex.z-dn.net/?f=45-11.25%20%3D%20%5C%2433.75)
Hence Randall earned $33.75 from selling baseball cards.
