Answer:
$ 7.7
Step-by-step explanation:
Given,
There are 18 $1 bills, ten $5 bills, eight $10 bills, three $20 bills, and one $100 bill,
Total number of bills = 18 + 10 + 8 + 3 + 1 = 40,

Thus,
The probability of $ 1 = 
The probability of $ 5 = 
The probability of $ 10 = 
The probability of $ 20 = 
The probability of $ 100 = 
If a bill is selected randomly,
The expected value of the bill



= $ 7.7
Answer:

Step-by-step explanation:
The average speed of the Erin is 120/16 mph
Here,
Numerator = 120
Denominator = 16
mph = miles per hour
We need to find an expression expressed as a decimal.
So,

So, the final answer is
.
The answer is D because -10+(-40)+(-90) is the same just swiched
If 30 is half price, then what is full price?
You can set up this problem like this:
30 = x/2
OR
30 = (1/2)x
where x is the full price.
To solve, simply multiply each half by 2:
2(30) = 2((1/2)x)
<u>x = $60</u>
