I am not sure how to do this question
I will be happy to check your work.
dose in milligrams= 136/(25*29)
To find the proper dosage for a dog that weighs 29 pounds, you need to substitute the weight (x = 29) into the dosage formula D(x) = 136/25x. Let's calculate it step by step:
1. Start with the given dosage formula: D(x) = 136/25x, where x represents the weight of the dog in pounds.
2. Substitute the weight of the dog, which is 29 pounds, into the formula: D(29) = 136/25 * 29.
3. Simplify the expression: D(29) = 136/25 * 29 = 136/25 * (29/1) = (136 * 29) / (25 * 1).
4. Calculate the numerator: 136 * 29 = 3944.
5. Calculate the denominator: 25 * 1 = 25.
6. Divide the numerator by the denominator: D(29) = 3944 / 25 = 157.76 (rounded to two decimal places).
Therefore, the proper dosage for a dog that weighs 29 pounds is approximately 157.76 milligrams.
