Part B: At practice the next day, Derrick made 54 baskets out of 70 attempts. Describe how Derrick's overall percentage for the two days compares to his percentage for the previous day. Justify your answer.

ANSWER:
The percentage of the first day is above the general percentage and the percentage of the second day is below the general percentage
STEP-BY-STEP EXPLANATION:
The first thing is to calculate the percentage of this new day, just like that
[tex]\frac{54}{70}\cdot100=77.14\text{\%}[/tex]Now, to calculate the general percentage, you have to add the attempts and add the baskets:
[tex]\frac{66+54}{80+70}\cdot100=\frac{120}{150}\cdot100=80\text{\%}[/tex]
