Answer:
the answer is 19
Step-by-step explanation:
count with your figures 10 fingers add 9 and 19. :))))
I am assuming that the cost of an oil change already includes the mark-up.
So, 18 is 175%. 18 ÷ 1.75 = 10.29 is the original cost.
10.29 * 3/4 = 30.87/4 = 7.71 mark-up
10.29 + 7.71 = 18
Or if 18 is the basis of the mark-up, then,
18 * 3/4 = 54/4 = 13.50 mark-up
18 + 13.50 = 31.50 new cost of an oil change
Answer:
0.33
Step-by-step explanation:
Let P(S10) be the probability that surviving for 10-years after being diagnosed with a particular cancer
And P(S5) be the probability that surviving for 5-years after being diagnosed with a particular cancer
We have
P(S5)=0.6 and P(S10)=0.2
And we have the conditional probability equation:
where
- P(S10|S5) is the probability that surviving for 10-years after being diagnosed with a particular cancer given that survived for 5-years after being diagnosed with a particular cancer
- P(S5|S10) is the probability that surviving for 5-years after being diagnosed with a particular cancer given that survived for 10-years after being diagnosed with a particular cancer (which is 1 because if you survived 10 years, you already survived 5 years)
Then
A=P(1+r)^t
P=500
r=0.06
t=15
Thus A=500(1.06)^15=1198,279
