The nurse vaccinated 52 people on wednesday, 58 on Thursday and 43 on Friday.

The flu vaccine costs R49,00per vaccine and the hepatitis vaccine costs R98,00

B) if approximately half the people had flu vaccines and the other half had hepatitis vaccines, estimate how much money was spend on vaccines

1 answer

To estimate how much money was spent on vaccines, we first need to determine the number of people vaccinated for each type of vaccine.

  1. Calculate the total number of people vaccinated:

    • Wednesday: 52 people
    • Thursday: 58 people
    • Friday: 43 people

    Total = 52 + 58 + 43 = 153 people

  2. Since approximately half received flu vaccines and the other half received hepatitis vaccines:

    • Number of flu vaccines = 153 / 2 ≈ 76.5 (we can round this to 76 for the calculation)
    • Number of hepatitis vaccines = 153 - 76 = 77
  3. Calculate the cost for each type of vaccine:

    • Cost of flu vaccines: \[ 76 \text{ vaccines} \times R49.00/\text{vaccine} = R3,724.00 \]
    • Cost of hepatitis vaccines: \[ 77 \text{ vaccines} \times R98.00/\text{vaccine} = R7,546.00 \]
  4. Now add the costs of both vaccines: \[ R3,724.00 + R7,546.00 = R11,270.00 \]

Thus, the estimated total amount spent on vaccines is R11,270.00.
