Question

Complete this table showing the amount of penicillin that will remain active in the Women's blood at intervals of
one hour from 0800 until 1100 hours
​

Answer 1

Answer:

0800 - 300g

0900 - 180g

1000 - 108g

1100 - 64.8g

Step-by-step explanation:

Given: A woman in hospital receives an injection of penicillin. Her body gradually breaks the penicillin down so that one hour after the injection only 60% of the penicillin will remain active. This pattern continues: at the end of each hour only 60% of the penicillin that was present at the end of the previous hour remains active. Suppose the woman is given a dose of 300 milligrams of penicillin at 8 o’clock in the morning.

Solution:

60% remains after one hour.

Woman has 300g of penicillin in her body at 0800

So at 0900, the woman will have 60/100 * 300 = 180g.

At 1000, the woman will have 60/100 * 180 = 108g

At 1100, the woman will have 60/100 * 108 = 64.8g
