The total number of tickets sold is an illustration of proportions
The number of tickets sold is 20
The proportion of tickets sold is given as:
p = 1/4
The number of tickets left is given as:
n = 60
If he sells 1/4, then the proportion of tickets left is:
q = 1 - p
This gives
q = 1 - 1/4
q = 3/4
Let the total number of tickets be N.
So, we have:
3/4 * N = 60
This gives
N = 60 * 4/3
Evaluate the product
N = 80
The number of tickets sold is then calculated as:
Sold =80 - 60
Sold = 20
Hence, the number of tickets sold is 20
