She would make 3.00 dollars
50(10) - 20(10) = (10)(50 - 20)
500 - 200 = (10 * 30)
300 = 300
(10)(50 - 20) = 30(10)
(10 * 30) = 300
300 = 300
Answer:
30/552
Step-by-step explanation:
In order to solve this problem you need to multiply the probability of getting grape for the first gumball with the probability of getting grape for the second gumball. Since there are 6 grape gumballs and a total of 24 gumballs (6*4). Then the probability of getting grape for the firs one is

Now there are only 5 grape gumballs available and one less in the total supply, therefore the probability of getting grape in the second try is

Finally we multiply them together to find the probability of getting two grapes in a row.
= 
I believe the answer is 7
You need to make 225 and 187.5 into a fraction like 187.5/225 then compare that to ?/100 to that you need to figure out what 225 divided by 100 is then divide that answer by 187.5. 225/100=2.25 187.5 divided by 2.25 is 83.3. 100- 83.3= 16.7 percent. You're right if you round it
