Question

Alison is selling and buying baseball cards online. She sells each card for $3.25 and buys each card for $5.50. If she sold 4 cards and bought 7 cards, did she end up making money or spending money and how much money did she spend or make? A) she made $0.75 B) she made $51.50 C) she made $25.50 D) she spent $25.50 E) she spent $51.50

Answer 1

Each card she sells cost $3.25.

y = 3.25s

y = 3.25(4) = 13

Each card she buys cost $5.50.

y = 5.25b

y = 5.25(7) = 38.5

She spent 38.5 dollars in total. However, you need to subtract the money she earned by the total cost.

38.5 - 13 = 25.5

She paid 25.5 dollars out of her own pocket, including the money she earned from selling cards she paid 38.5 dollars.

So the answer is "She spent $25.50"

Let me know if it's correct

Answer 2

Income :
she sells each card for 3.25....and she sells 4 cards...so she made :
3.25(4) = $ 13.

expenses :
she bought each card for 5.50...and she bought 7 cards....so she spent :
5.50(7) = 38.50

so she spent more then she made

income - expenses = balance...
13 - 38.50 = -25.50...so she ended up spending 25.50...answer D
