Brett has a $30 online gift certificate. He plans to buy as many books as he can. The cost of each book is $4. There is also a s
ingle shipping charge of $2. How many books can he afford without spending more than his gift certificate amount?
1 answer:
Answer:
7 books
Step-by-step explanation:
make an equation
x = # of books each book is $4 so its 4x
the shipping fee no matter how many books he buys will be $2 so it's just 2
the equation looks like this:
4x + 2 = 30
we set equal to 30 cuz he can't spend more than $30
solve for x
4x = 30 -2
4x = 28
x = 7
Brett can buy no more than 7 books.
