Amanda sold 6 of 12 stickers which she had bought at $0.75 each and the remaining stickers at $0.40 each show by calculation ,whether amanda made a profit or loss on buying and selling the stickers

2 answers

did each sticker cost $0.75? If so, you don't say the selling price.
or did she sell 6 of them for $0,75 each? If so, you don't say what they cost her.

In any case, find the cost of all 12,
find the revenue from selling 6 at one price and 6 at $0.40
compare cost vs revenue
No she didnt
