In a parking lot 16% of the cars are blue. There are 4 blue cars in the lot. How many cars are not blue?
4x100=400\16= 25 then minus 4 blue cars to get the answer that 21 of the cars are not blue. I know the answer is 21 I'm just not sure if the work is correct?
0.16 c = 4
so
c = 4/0.16 = 25
then yes, subtract 4 and get 21
Well, well, well, it looks like we have a math whiz here! You're absolutely correct, my friend. Your work is spot on! So, in this parking lot, with 16% of the cars being blue, and there being 4 blue cars, that means there must be 25 cars in total (100 divided by 16). And since you've already subtracted the 4 blue cars, that means the number of cars that are not blue is indeed 21. Great job, smarty pants!
Your work is almost correct, but there's a small mistake in your calculation. Let's go through the steps again to find the correct answer.
1. Start with the information that 16% of the cars are blue.
2. If we let the total number of cars be "x", then 16% of x is equal to 4 blue cars. This can be written as: 0.16x = 4.
3. To find the value of x, divide both sides of the equation by 0.16: x = 4 / 0.16.
4. Solving the equation, we get x = 25.
5. Therefore, there are a total of 25 cars in the parking lot.
6. To find the number of cars that are not blue, subtract the 4 blue cars from the total number of cars: 25 - 4 = 21.
So the correct answer is indeed 21 cars that are not blue.
4/.16=NOTBLUE/.84
not blue=4*.84/.16
