Kate sells cakes. She has 80 cakes to sell for £3 each Kate sells 50 cakes before reducing the price by 40%. She then sells the remaining cakes at the reduced price It costs Kate £95 to make the cakes. Her target is to make a profit of at least £100.
I've multiplied the selling price with the amount of cakes sold and the balance with the reduced selling price but I am still getting the wrong answer
Working
30 cakes @ £1.20=£36 (40% of £3) 50 cakes @ £3:00=£150
£150 + £36=£186
I believe the problem is in the computation of the new price. Reducing the price by 40% means that the new price is the old price minus 40% of it. It would be $3 - 3 \times 0.4 = 3 - 1.2 = 1.8$. Giving you $30 \times 1.8 = 54$£ for the 30 last cakes. In total 204£.
