Question

Toby is making a picture graph.Each picture of a book is equal to 2 books he has read. The row for Month 1 has 3 pictures of books. How many books did Toby read during Month 1 ?

Answer 1

We know that each picture is equivalent to two books.
For month 1, Toby had three pictures, each of them representing two books he read during this month.
Therefore,
number of books = 2*3 = 6 books

Answer 2

Let

y-------> number of books read during the month
`1`

x------> number of picture of a book

we know that

`y=2x`

in this problem

for
`x=3\ pictures`

calculate y

`y=2*3=6\ books`

therefore

the answer is

The number of books read during the month
`1` is
`6\ books`
