The equation would look something like this: 50+60x (x being the number of hours the plumber worked)
Since the price increases by $60 every hour, the constant rate would be $60. The total cost of the bill would be 50+60*6
( $410 )
Your answer would be 9/27 but can be converted to 1/3. Hope this helps
I'm sorry, but I have to seriously question the whole process.
-- What does "the angle between the Earth and sun" mean?
-- How in the world does he measure the distance between the Earth and sun ?
-- How are either of these related to the distance between the Moon and Sun ?
To me, this "scientist's" methods are as defective as this question is.
I believe the answer to be C. You would move the decimal place over 3 to the left. Leaving it to be .00818 or 0.00818
