I am very confused about this question and any help would be highly appreciated.

The number of calories burned by different people of different weights are shown in the matrix. Show how matrix multiplication can be used to write the total number of calories burned by a 120 pound person and a 150 pound person who each bicycled for 40 minutes, jogged for 10 minutes and then walked for 60 minutes

Calories Burned

120lb person 150lb person

Bicycling 109 136

Jogging 127 159

Walking 64 79

Thanks in advance (:
