Answer:
1.35
Step-by-step explanation:
We need to identify our independent variables and dependent variables.
The number of papers graded depend on the amount of time.
- The amount of time is the independent variable
- The papers graded depends us the dependent variable
Divide the independent variable by the dependent variable to find papers per minute
- For Ms.Mitchell the papers per minute is
- [tex] \frac{30}{8} = 3.75[/tex]
- For Mr.Rector, the papers per minute is
- [tex] \frac{24}{10} = 2.4[/tex]
- Subtract 2.4 from 3.75.
[tex]3.75 - 2.4 = 1.35[/tex]
The answer is 1.35
