Practice makes perfect
We want to know the number of pounds n per 5 dollars. To do this, we will use the information in the graph to calculate the unit rate.
Let's write a ratio to show the rate 1 pound per 2 dollars.
1pound/2dollars or 1/2
To find the unit rate, we write an equivalent rate with a denominator of 1.
