Answer:
Profit = $ 5
Step-by-step explanation:
Money spent on supplies = $ 20
Number of cups of lemonade sold by her = 100
Selling price for 1 cup of lemonade = 1 quarter = $ 0.25
∴ Selling price for 100 cups of lemonade = 
So, Christie can make $ 25 from 100 cups of lemonade.
Profit made by her = Selling price - Money spent on supplied
= $ 25 - $ 20 = $ 5.
Answer:
I would have to see the line to answer the question.
X^2-12x-9=0
Add 9 to both sides
x^2-12x=9
Add (b/2)^2 to both sides
x^2-12x+36=45
Factor
(x-6)^2=45
So C is the answer
Answer:
0.271 or 27.10%
Step-by-step explanation:
If the present month is January, in 16 months there will be three space shuttles launched (two in June and one in October).
The probability that at least one launch will be delayed is 100% minus the probability that no launch will be delayed:

The probability that at least one of the launches in the next 16 months will be delayed is 0.271 or 27.10%.
Answer:
Well as a fraction it would be 2/5, if you would like it as a number you divide 300 by 3/5 and use the leftovers.
