What does a count add each time?
Short answer. 1.
For prices 15, 10, 20, what are the total and count?
45 and 3.
Remember
| Total: add the value |
| Count: add 1 |
Counting and totalling look alike. What is the difference? T is the total and n is the count. Both start at zero. T adds each price. N adds one each time. Two rules to keep. Total adds the value. Count adds one.
