Answer:
$ 2.33
Step-by-step explanation:
Fair game is when expected profit = 0
0.3(X) + 0.7(-1) = 0
0.3X = 0.7
X = 7/3
Approximately 2.33
Answer:
y=-5/4x+5
Step-by-step explanation:
The line goes down 5 for every 4 to the right, and it crosses the y-axis at (0,5).
This is asking for x and y coordinates. for example, 1 ticket is $34, right? so on the x side, there is a 1, and on the y side theres a 34. the order pair would be (1, 34). then graph it. the equation would be y=34x. hope this helps!
D + q = 110......d = 110 - q
0.10d + 0.25q = 20.30
0.10(110 - q) + 0.25q = 20.30
11 - 0.10q + 0.25q = 20.30
-0.10q + 0.25q = 20.30 - 11
0.15q = 9.30
q = 9.30/0.15
q = 62 <==== there are 62 quarters
d = 110 - q
d = 110 - 62
d = 48 <==== there are 48 dimes
