A bottle of ear drops contains 10 mL. The drops are used four times daily and each time, 0.05 ml is used per drop. How many days will a bottle last

Sagot :

How many days will a bottle last?

It'll last for 50 DAYS

MY OWN EXPLANATION :

If the person uses 0.05 ml for 4 times a day, means that person uses 0.2 ml daily.

Let's divide 10ml to 0.2 ml

Tha answer is : 50

Then the ear drops will last for 50 days

How can i prove that my answer is correct?

If we use 0.2 ml daily and it's enough for 50 days, then how many ml we will use for 50 days?

Let's multiply 50 days to 0.2 ml

The answer is 10 ml

So basically, the answer is IT'LL LAST FOR 50 DAYS
