Answer 1

The correct answer for the question that is being presented above is this one: "b) (32,28)." Dr potter provides vaccinations against polio and measles. Each polio vaccination multi-dose vial consists of 44 individual doses, and each measles vaccination multi-dose consists of 22 individual doses.

Answer 2

Answer: b) (32,28)

Explanation:

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

According to the question,

`x+y=60....(1)\\44x+22y=2024.....(2)`

Dividing 22 on equation (2) both sides, we gwt

`2x+y=92....(3)`

Subtract (1) from (3), we get

`x=32`

Substitute x=32 in equation (1), we get

`32+y=60\\\Rightarrow\ y=60-32\\\Rightarrow\ y=28`

Hence, Dr. Potter gives 32 individual polio vaccination and 28 individual measles vaccinations .
