Let x = the minutes that Tom has remaining before exceeding 500 minutes.
Because he has already used 230 minutes, the total minutes he has is
x + 230
We want this total to be less than or equal to 500 minutes.
Therefore
x + 230 ≤ 500
Answer: x + 230 ≤ 500

<h3>What is weight?</h3>
The weight of matter is found as the product of the mass and the gravitational acceleration.
Unit conversion;
1 lb =0.45 kg.
Dosage of a drug = 200 mg / kilogram
John weighs = 80 lb
1 lb =0.45 kg.
80 lb = 36 kg
According to the weight the drug should he receive is;
Dosage of a drug = 200 mg / kilogram × 36
Dosage of a drug = 7200 milli gram
Hence, John should receive about 7200 milligrams of the drug.
