The equation would be 55h+40=c
h-hours
40-Initial value-Price paid at start
c-total cost
so if you plug the numbers in, 55h+40=190
Subtract 40 from both sides, 55h=150
Divide both sides by 55, h=150/55
150/55=<span>2.72727272727
and that rounds to 2.73</span>

Complete Question
A few years ago, people tended to have relatively large CD collections. For students at a large university in the midwest, the mean number of CDs owned was 78 with a standard deviation of 90. To confirm these numbers, a random sample of 120 students from this university was collected and the size of their CD collections recorded. These particular 120 students had a mean CD collection size of 80 CDs. What is the numerical value of the sample mean?
Answer:
Sample Mean 
Step-by-step explanation:
From the question we are told that:
Population Mean 
Standard deviation 
Sample size 
Sample Mean 
Therefore
The numerical value of the sample mean is
Sample Mean 
593281.12x10^6
all 10^6 means its basically .12 and add 10 zeros
