Answer:
D
Step-by-step explanation:
x-0.1x=36
where x is the original price
0.1x is the discount (10% of the original price)
36 is the price paid
x-0.1x=36
0.9x=36
----- ----
0.9 0.9
x=40
The original price is $40.00
Let's start by putting the information on the table into fraction form.
So:
O: 9/20
Y: 5/20
B: 6/20
We now know the probability of picking the different colour chips when the experiment is repeated 20 times but we want to know the probability if the experiment was repeated 80 times. So, we have to find out what number to multiply the probabilities by to get the answer over 80. So:
80/20 = 4
4x9 = 36
Thus the probability of picking an orange chip should be 36/80 and so she should expect to pick up 36 orange chips !
