Question

The dosage in milligrams D of a heartworm preventive for a dog who weighs x pounds is given by D(x) =136/25x.

Find the proper dosage for a dog that weighs 24 pounds.

Answer 1

130.56 mg

Explanation:

The equation might be written incorrectly. Given that for a heavier dog, a higher dosage is required, the equation that describes the dosage in milligrams of a heartworm preventive for a dog who weighs x pounds is:

`D(x) = (136)/(25)x`

If a dog weighs 24 pounds, than the dosage required for this dog is:

`D(24) = (136)/(25)*24\\D(24) = 130.56\ mg`
