Answer:
1. 108 comic books
2. 7 square tables
Step-by-step explanation:
Here's why:
1. Let J represents Joseph
Originally, J has 48 comic books but he sold ¼ of it.
J= 48÷ 4 = 12
So he sold 12 of it. He brought twice the number of comic books as he has now.
J = 48 - 12 = 36
J = 36 + (36×2)
J = 36 + 72
J = 108
Answer: Joseph has 108 comic books now.
2. Let P represent the pupils
There are 100 P in all. There are 9 rectangular tables with 8 pupils each and square tables with 4 pupils each.
Given: 9 rectangular tables with 8 pupils each
So, 9 × 8 = 72
72 pupils can fit 9 rectangular tables.
How many square tables are needed so that 100 P can read at the same time?
So, there are already 72 students can fit 9 rectangular tables.
100 - 72 = 28 students
28 students ÷ 4 = 7
Answer: 7 square tables are needed.
