Question

The book fair had a sale where 5 books were $36.90. If you wanted to buy 4books, how much money would you need?

Answer 1

Since the price of the 5 books is $36.90

Then we need to find the price of each book by dividing 36.90 by 5

`\begin{gathered} U\mathrm{}P=(36.90)/(5) \\ U\mathrm{}P=7.38 \end{gathered}`

The price of each book is $7.38

Now, to find the price of 4 books multiplying 7.38 by 4

`\begin{gathered} P=7.38*4 \\ P=29.52 \end{gathered}`

The price of the 4 books is $29.52
