Step-by-step explanation:

Add all of the weights of the first plane: 28 + 36 + 36 + 38 + 38 + 40 + 40 + 40 = 296 pounds. Now divide by 8 to find the average wieght of each luggage. 296/8 = 37 pounds/

Then add all of the weights of the second plane: 32 + 32 + 34 + 34 + 34 + 36 + 38 + 50 = 290 pounds. Now divide by 8 to find the average wieght of each luggage. 290/8 = 36.25 pounds.

Plane a has heavier luggage. Findind the average let's you know about how much each weighs.

Plane A has heavier luggage with a total weight of 2,360 pounds.

Plane B has 2,320 pounds.

Because each dot represents 8 luggage cases, you can multiply the weight times the corresponding number of luggage. for example, there are 8 cases of luggage that weigh 28 pounds. In total, those 8 equal 224 pounds.
