Question

In a bag of marbles, 12% were red, 16% were blue, and the rest are white. If the bag has 250 marbles how many were red or blue​

Answer 1

Answer: 70

Step-by-step explanation: First, let's find how many are worth each in numbers. Use this formula:

Part Percent * Whole number / 100

Plug in the numbers:

Red = 12 * 250 / 100

3000/100

= 30 red marbles

Blue = 16* 250 / 100

4000 / 100

= 40 blue marbles

40 + 30 = 70

White = 250 - 70

= 180 white marbles

We can check our answer by adding 12 + 16. That's 28. So by multiplying 250 by 28, we get 7000. 7000 divided by 100 = 70

70 = 70

Therefore, both statements are true
