Sarah wants to earn some extra money, so she decides to make and sell cards. She spends $27 on supplies and sells 15 cards for $3 each. How much money did Sarah earn or lose?
Ok, this is pretty straightforward, First I want you to tell me how much money Sarah made from the cards, keeping in mind that she sold 15 at 3 dollars each.
Do you know how to set that up?
45 dollars from selling the cards
Perfect! So now we need to find the difference from the 45 she made and 27 that she invested or used to make the cards.
Bravo! So that means that Sarah made 18 dollars from her "business" .
