<u>Answer:</u>
$50 and $115
<u>Step-by-step explanation:</u>
We know that,
the sum of the two rates = $165 per hour
Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.
Then combining their charges together to get:
Solving for x to get:
So the rate charged per hour by one mechanic is $50 and for the other mechanic = 
$115.
Like
you said: 10 beats per minute, which is 20% percent of its normal value.
So:
10 per minute is 20% of the normal rate. You will divide each side by 0.2, which
will result in 50 per min

A.) 3.2 pounds package has a shipping cost of $4.13. We can't use the cost assigned to 3 lbs because the package is over 3 lbs but it is not over 4 lbs so we use the cost of 4lbs.
b) It is better to use a line graph where x values represent the weight in pounds and the y values represent the cost.
c) f(x) = 2.69 + 0.48(x-1)
d) domain is the x values; range is the y values
