Answer:
They should reserve 19 rows
Explanation:
First let's write down what we know:
The number of students: 146
The number of teachers: 5
The number of chaperones: 8
Next, we must find the total number of people going to the theater:
So, we add the number of students, teachers, and chaperones together:
146 + 5 + 8 = 159
Total number of people: 159
Lastly, we must find how many rows they should reserve
We know that each row has 8 seats, which means 8 people are in each row
So, we must divide 159 by 8, in order to find the number of rows they should reserve
159 ÷ 8 = 19.875
So, they should reserve 19 rows
