The total change from the beginning of the day to the end of the day is 4 29/ 122
<h3>What is rate of change?</h3>
A rate of change is simply a rate that describes how one quantity changes in relation to another quantity.
If a is the independent variable and b is the dependent variable, then:
Rate of change = change in b/change in a
We have that;
- Beginning of the day = 30 1/ 2 = 61/ 2 points
- End of the day = 129 1/4 = 517/ 4 points
Total rate of change = 517/ 4 ÷ 61/ 2
= 517/ 4 × 2/ 61
= 517/ 2 × 1/ 61
= 517/ 122
= 4 29/ 122
Thus, the total change from the beginning of the day to the end of the day is 4 29/ 122
