Answer: Her measuring cup has 8.25 mL of medicine.

Step-by-step explanation:

As per given,

In 11 mL of medicine, there are 20 drops.

That means quantity in 1 drop = $\dfrac{11}{20}$ mL

Now , the quantity in 15 drops = 15 x quantity in 1 drop

= $15\times\dfrac{11}{20}$

$=\dfrac{33}{4}$

= 8.25 mL

Hence, her measuring cup has 8.25 mL of medicine.
