If a veterinarian administers four vaccines at $25.00 each, how much will the total charge be?

To determine the total charge for administering four vaccines at a cost of $25.00 each, you need to multiply the number of vaccines by the cost of each vaccine.

The calculation is as follows:

4 vaccines × $25.00 per vaccine = $100.00.

This means that the total charge for the four vaccines is indeed $100.00. This approach demonstrates basic multiplication and reinforces the understanding of unit pricing, which is crucial in veterinary practice for accurately billing clients for services rendered.
