Answer - equation is $226= 3x + $61
Answer to cost per hour is $55
Step by step
We know the total spent is $226
We know the labor hours is 3
We know the parts cost (y intercept) is $61
We need to find x the cost per hour
$226=3x +$61
Subtract $61 from both sides to isolate x
$165 = 3x
Now divide both sides by 3 to solve for x
$55 = x
You can check your work by substituting $55 for x in your equation
$226 = (3)(55) + $61
$226 = $165 + $61
$226 = $226

Help on question 30!!
Basile [38]
The given identity tells you ...
.. (sum of numbers) * (sum of squares - product) = (sum of cubes)

Substituting the given information, you have
.. (sum of numbers) * (29 -10) = 133
Then you can divide by (29 -10) to get
.. sum of numbers = 133/19 = 7

The sum of the two numbers is 7.
