Ilyas has a $50 online gift voucher. He plans to buy as many books as he can with it. The cost of each book is $4. There is also a single shipping charge of $7.50. How many books can he afford without spending more than his gift voucher amount?

Answer:

10 books

Explanation:

50-7.50=42.5

42.5÷4=10.625

but that means it is only 10 books as there is no 10 and a half book

Answer:

10

Explanation:

Set up an inequality

4x + 7.50
\leq 50

4x
\leq 42.50

x
\leq 10.625

So the answer is 10 because you can't buy .625 of a book
