Answer:

4. 4 tablets

5. no, 5 tablets

6. 19320 mg, 19.32 g

Step-by-step explanation:

4. 500 ÷ 125 = 4 tablets

5. a) no

b) 150 ÷ 30 = 5

you should be given 5 tablets

6. There are approximately 2.205 lbs in one kg.

Therefore, 142 lb = 142 ÷ 2.205 = 64.4 kg

300mg/kg/day

Therefore, number of mg per day = 300 x 64.4 = 19320 mg

b) As 1000mg = g

19320 ÷ 1000 = 19.32 g (nearest hundredth)
