Question

A livestock vaccine is to be given at the rate of 2 milliliters for each 13 pounds of body weight. How much should be given to a 78-pound goat?

1) 14 milliliters
2) 12 milliliters
3) 10 milliliters
4) 8 milliliters

Answer 1

To find the amount of vaccine to give to the goat, use a proportion. The correct amount is 12 milliliters.

Step-by-step explanation:

To determine the correct dosage of the livestock vaccine for a 78-pound goat, we use the given rate of 2 milliliters for each 13 pounds of body weight. We first divide the goat's weight by the weight unit for dosage:

78 pounds ÷ 13 pounds = 6.

Next, we multiply this value by the milliliters of vaccine per weight unit:

6 × 2 milliliters = 12 milliliters.

Therefore, a 78-pound goat should be administered 12 milliliters of the vaccine.
