PART ANSWER:
Hi. I don't know the entire answer but I do know the probability of chosing a blue marble once is 25%.
5 + 3 + 2 + 2 = 12
3/12 or 1/4 = 25% or .25
Sorry I could not fully help.
3 + 4 = 7
84 ÷ 7 = 12 = 1 (in terms of the ratio)
12 × 3 = 36, which is the answer
Hope this helps :)
Answer:
25% of 200 is 50
Step-by-step explanation
40% of a number is 80
.40 * n = 80
Divide each side by .4
.40 n/.4 = 80/.4
n = 200
The number is 200
Now lets find 25 percent of that number
.25 * 200 = 50
5,000 is the answer to the equation
