suppose you write a book. the printer charges $4 per book to print it, and you spend $5500 on advertising. you sell the book for $15 dollars a copy

25.46 - (18.78 - 5.68)
First, always work out the brackets. HINT: Brackets mean to multiply.
So, first we take 25.46, and as I said before, brackets mean to multiply.
First, we have to find out what is in the brackets — we have to take away :
18.78 – 5.68 = 13.1
Then we take 25.46 and MULTIPLY 13.1
The answer is 333.5(correct to 1 d.p)
Hope this helps
