A car dealer has 395 cars on the lot.

Of these cars, about 15% are red.

Which is the best estimate of the

number of red cars on the lot?

A.

B.

C.

D.

40

60

70

80

B 60

Step-by-step explanation:

Finding the exact percentage of 395 gets you to 59.25. Rounding it gets you to 60 so that would be your estimate.

To find the percentage of something, you have to take the percentage and move the decimal 2 spots to the left (%15 = 0.15)

You then just multiply, ignoring the decimal to get 5925

After that, you have to place the decimal. There's 2 numbers to the right of the decimal so you move the decimal 2 places to the right in your final answer to get 59.25

B. 60

Step-by-step explanation:

Start by estimating 10% = 40

Then do 1/2 if that = 20

add them to get 60 cars

or 15 for every 100 15x4=60
