Question

Three times the number of red marbles in a bag is the same as 33 1/3 percent of the number of red marbles in the bag increased by 64. How many red marbles are in the bag?

Answer 1

Answer:

24 red marbles

Step-by-step explanation:

Ok, why not let  R = number of red marbles.

The first sentence says:

3 * R =  (33 and 1/3) % * R  + 64

or

3R = 100/3 %*R + 64

3R = (1/3)*R  + 64

9R = R + 192

8R  = 192

R = 24 red marbles
