Answer:

A dosage of 3 tablets is required for a child weighing 53 pounds.

Explanation:

1 pound equals 0.4536 kilograms.

Therefore, 53 pounds equals $(53\times 0.4536)kg=24 kg$ .

This means the child's weight is 24 kg.

The recommended dosage is 10 mg for each kilogram of body weight.

Hence, for a body weight of 24 kg, the advised dosage is $(10\times 24)mg$ , which equals 240 mg.

Each tablet contains 80 mg of acetaminophen.

Thus, 240 mg of acetaminophen corresponds to $\frac{1}{80}\times 240$ tablets, equating to 3 tablets.

Therefore, for a 53-pound child, 3 tablets are necessary.

To convert 53 pounds into kilograms, divide by 2.2, resulting in approximately 24.09 kilograms. This can be rounded to 24 kg. When applying the recommended dosage of 10 mg per kilogram, for 24 kg, the total dosage is 240 mg. Dividing this by 80 gives 3. Thus, a child weighing 53 pounds needs 3 tablets for the correct dosage.
