You can use the greatest common factor to simplify fractions.
A ratio is an expression that tells us the quotient of two numbers.
The expected value of the outcome of the bid is $0.18
So let's start by counting how many bids are placed up to a total of 160.
100*160 = 16000.
What will be your arbitrary bid? As each bid has an equal chance of success, the average of all bids is used. (One cent plus 160 dollars) / 2 = 80 dollars (rounded)
Your odds of winning are 1/16000 (1 bid out of 16000).
If you win, your profit is 1920 ($2000 minus $80.00).
1920/16000 is $0.12
Your cost to enter the auction is $1, and your average winning offer is $0.12.
The result is $0.18 (0.12-1=-0.88).
Thus the expected value of the outcome of the bid is $0.18

Answer:
y=1/8x - 3
Step-by-step explanation:
Se did not got an A, as you said she needs at least 90% right and she only got 80% right. She had to score at least 18 of the questions correct.
16/20=80/100
16*5=80
18*5=90
4 2/3 because 3 times 4 = 12 so there would be 4 wholes and 2/3 left
