Answer:
81
Step-by-step explanation:
12/3 = 4
4 - 2 = 2
x = 2
using the order of operations, you would first have to do y + 3
y = 12
12 + 3 = 15
the equation simplified is 3 x 2 + 5 x 15
3 x 2 = 6
5 x 15 = 75
75 + 6 = 81
You originally start out with 28 marbles. each marble has a number out of 28 to create a percentage. 21/28 or 75% signifies red, 4/28 or about 14% is white and 3/28 or about 11% is gray. add white and gray, which is 7/28 combined or 25% together. multiply by number of times the process is completed, which is 112 and the final answer is 28
The answer is going to be B.
