Seven out of every 8 students surveyed owns a bike. The difference between the number of students who own a bike and those who do not is 72. How many students were surveyed? A total of students were surveyed

Number of student (not Bike) = 12

Number of student (Bike) = 84

Total student = 96

Step-by-step explanation:

Given:

Probability of student have bike = 7/8

Computation:

Assume;

Number of student (Bike) = a

Number of student (not Bike) = b

So,

a-b = 72

So,

a / (a+b) = 7/8

8a = 7a + 7b

a = 7b

So,

a-b = 72

7b - b = 72

6b = 72

b = 12

Number of student (not Bike) = 12

Number of student (Bike)

a -12 = 72

a = 84

Number of student (Bike) = 84

Total student = 84 + 12

Total student = 96

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
