Answer:
The number of tickets must be sold is 2500
Step-by-step explanation:
The charge for each ticket = $ 5
The concessions amount = $ 1400
The amount paid to players = $ 2000
The amount paid to workers = $ 1600
The cost of each bag given to each fan = $ 3 per bag
Let The number of tickets sold = x
Now, number of ticket sold = number of fans = x
So, According to question
( charge per ticket × number of fans - cost of each bag × number of fan - concession amount ) = amount paid to players + amount paid to workers
Or, $5 x - $3 x - $1400 = $2000 + $1600
Or, $2 x = $3600 + $1400
Or, $2 x = $5000
∴ x = = 2500

Let x be the number of polio individual doses and y be the number of each measles individual doses.
Then the number of polio vaccination = 44x
The number of measles vaccination multi-dose = 22x

Subtract (1) from (3), we get
Substitute x=32 in equation (1), we get
Hence, Dr. Potter gives 32 individual polio vaccination and 28 individual measles vaccinations .
