Question

Wendy recently opened a burger joint. Help her find the difference in the maximum and minimum number of burgers sold by the joint over the course of 5 days.

Answer 1

To find the least number of burgers sold, we need to look for the smallest value on the Y-axis of all the given points.

To find the maximum number of burgers sold, we need to look for the highest value on the Y-axis of all the given points.

From the graph, we can see:

Least number of burgers sold in a day
= 10

Maximum number of burgers sold in a day
= 60

$\therefore$ Difference between the maximum and the minimum number of burgers sold
= 60 - 10
= 50
