Answer:
The rate charged by the first mechanic was $65 per hour and the rate charged by the second mechanic was $105 per hour
Step-by-step explanation:
Let
x ----> the amount charged per hour by the first mechanic
y ----> the amount charged per hour by the second mechanic
we know that
the sum of the two rates was $170 per hour
so
----> equation A
Together they charged a total of $1825
so
----> equation B
solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (65,105)
see the attached figure
therefore
The rate charged by the first mechanic was $65 per hour and the rate charged by the second mechanic was $105 per hour
Answer:26
Step-by-step explanation: So you would subtract the total number they have now from what they had before and that would equal what was donated!
Mean: add all of the values together and then divide by the number of values
mean= 47.857
Median: like up the numbers least to greatest and then find the number in the middle. if there is an even number of values, take the average of the two middle values
median= 45
The mean reflects the beet measure of the center.
