During the summer, Sarah picks watermelons for her uncle. The table shows the number of wagon loads, x, and the number of watermelons Sarah can haul, y. What is the unit rate in watermelons per wagon load?

D 16
To find the unit rate in this situation, we need to find how many watermelons Sarah can haul in one wagon load.
We can do this by dividing the number of watermelons, y, by the number of wagon loads, x.
For example, for the first row of the table, the unit rate would be 8 watermelons divided by 1 wagon load, which equals 8/1 = 8.
We can do this for each row of the table to find the unit rate:
1 wagon load = 8 watermelons
2 wagon loads = 16 watermelons
3 wagon loads = 24 watermelons
4 wagon loads = 32 watermelons
In each case, the number of watermelons is the same as the number of wagon loads, so the unit rate is 8, which is answer choice B.
