- How much medicine will she need for one day?
- How much medicine in all for 5 days?
Solution
(a) One injection contains 5 mL of medicine
She requires 3 injections a day
So she needs medicine in one day = 5 mL × 3 = 15 mL of medicine.
(b) In one day she is getting 15 mL of medicine.
So, in 5 days medicine in all = 15 mL × 5 = 75 mL.
