Answer:
29
Explanation:
First, let's find out how many members are added to the squad with the new coach:
45% of 20 = 0.45 x 20 = 9
So, with the new coach, there are 9 more members added to the squad.
Now, to find the total number of members on the squad with the new coach, we just need to add the old number of members (20) to the number of new members added (9):
20 + 9 = 29
Therefore, there are now 29 members on the cheerleading squad at Morristown High School with the new coach.
