1. A school has 10 classes with the same number of students in each class. One day, the weather was bad and many students were absent. 5 classes were half full, 3 classes were 3/4 full and 2 classes were 1/8 empty. A total of 70 students were absent. How many students are in this school when no students are absent?


2. A telephone company charges initially $0.50 and then $0.11 for every minute. Write an expression that gives the cost of a call that lasts N minutes.

Sagot :

N - number of students in one class 
70 - number of absent students 
absent in each of the classes: 
5 x 1/2N   -   5 classes were half full, 
3 x 1/4N   -   3 classes were 3/4 full 
2 x 1/8N   -   2 classes were 1/8 empty 

(5 x 1/2N) + (3 x 1/4N) + (2 x 1/8N) = 70 
N = ? 

How many students are in this school when no students are absent?
