I calculated everything correctly until 53million vaccines (the second to last step). Then I got lost calculating the final revenue of 1.8billion. Could any member in the community please show me the following steps so I can find my mistake. My final revenue was found to be 5.3billion.
Thank you!
The actual kids who will take your vaccine is ~26m
The vaccine needs 3 does to work - 1 every 6 months.
But in a year they can only take 2 does. So, 26 * 2 = 53 units of vaccine
Now 3 vaccine = 100
1 vaccine = 33
26m * 2 * 33 = 1716m = 1.716B
Realistically the biggest proportion of children will get only 2 vaccines per year (let's say in March and in September; not in January/June/December). That would mean if your 26.67M customers are due to pay 100 euro for 3 vaccines, they will actually pay 66 euro for 2 vaccines (making the total number of vaccines 53M as you suggested).
26.67M people x 66 euro =1.8B or another to put this is: 53M vaccines x 33 euro = 1.8B
