Part A: Sydney made $18.50 selling lemonade, by the cup, at her yard sale. She sold each cup for $0.50 and received a $3 tip from a neighbor. Write an equation to represent this situation. (4 points)

Part B: Daria made a profit of $21.00 selling lemonade. She sold her lemonade for $0.75 per cup, received a tip of $3 from a neighbor, but also had to buy each plastic cup she used for $0.10 per cup. Write an equation to represent this situation. (4 points)

Part C: Explain how the equations from Part A and Part B differ. (2 points)

Please help (Ithink imma fail a math exam if not)

Answer:Part A answer:0.5x + 3 = 18.50How I got the answer:0.5 means how much money she made from each cup. the variable x = how many she sold. 3 equals the tip from the neighbor. and 18.50 is the total pricePart B answer:(0.75x – 0.10x) + 3 = 21.00How i got the answer:0.75 is how much money she make from each cup. 0.10 means how many she paid for each cup she used. x = how many cups were sold/bought (should be the same number!). 3 is the tip. and 21.00 is the total price made.Part C answer:The equations differ because Sydney didn’t have to pay for the cups she used, while Daria did. Although they did have the same amount for a tip, Daria made more money than Sydney.——————————————————————————————

this should be correct! hopes this help and i wish you good luck on your math exam!
