Emily has her own business making and selling greetings cards.
Each card costs her 68p to make. One day, Emily has 300 cards to sell.
She sells 65% of them for 99p each, and the rest for 75p each.
How much profit did Emily make?
First find out how many cards Emily sells for 99p each: 300 cards * 65% = <<300*65*.01=195>>195 cards
Then find how much Emily earns from selling the 99p cards: 195 cards * 99p/card = <<195*99=19205>>19205p
Then subtract the cost of making those cards to find the profit: 192.05 - 195 * 68 = <<192.05-195*68=-9975>>-9975p
Then find how many cards Emily sells for 75p each: 300 cards - 195 cards = <<300-195=105>>105 cards
Then find how much money Emily makes from selling those cards: 105 cards * 75p/card = <<105*75=7875>>7875p
Then subtract the cost of making those cards to find the profit from them: 7875p - 105 cards * 68p/card = 3565p
Finally, add Emily's profit from both sets of cards to find her total profit: 3565p - 9975p = <<3565-9975=-6410>>-6410p. Answer: \boxed{-6410}.
