Maths GCSE Percentage change question

Johan publishes a monthly poetry magazine. In March he printed 1400 copies of his magazine. In April he increased his print run by 15%.

It costs Johan £800 plus 75p per copy to print his magazine. He sells each issue for £1.99.

Assuming Johan sells every copy that he prints, calculate his percentage profit in April.

I got 27.8% as the percentage profit but in the book I'm working from it says the answer should be 59.6% so wondering where I went wrong?

You are answering a different question from the one asked.
Your profit for April is correct.
Just use this and the cost for April to calculate the profit in April.

Got it, thanks a lot!
(1.15*1400*1.99) = selling price (SP)
(800 + 0.75(1.15*1400) = money spent

Therefore profit percentage = (SP-Cost/Cost)*100 = 59.6%
