I wish I knew this one also
To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer

C) 
<h2>
Why?</h2>
To solve the problem, we need to remember the product of powers with the same base property, the property is defined by the following relation:

If we are multiplying two or more powers with the same base, we must keep the base and add/subtract the exponents.
So, we are given the expression:

We can see that both powers have the same base (4), so solving we have:

Hence, we have that the correct option is:
C) 
Have a nice day!
