Answer 1

The graph in the question shows the relationship between the price and the number of plates.

We can deduce that

The price of 4 plates is $7

We can use the information to get the unit price

By cross multiplying

The unit price can be calculated as:

`\begin{gathered} x=\frac{1*\text{ \$7}}{4} \\ \\ x=\frac{\text{ \$7}}{4} \\ \\ x=\text{ \$1.75} \end{gathered}`

Thus, the answer will be $1.75
