question 5
which might be a reasonable explanation for why sparkles and shines business owners seem to take in very different amounts of profit per hour worked?
the owner of shine seems to spend less on cleaning supplies than the owner of sparkle does.
the owner of sparkle seems to charge less per hour for cleaning services than the owner of shine does.
the differing amounts of hourly profit between the two companies are random and happen by chance.
the cost per hour for sparkles employee is much greater than shines cost per hour for supplies.

Explanation:

Profit per hour is calculated as (revenue per hour - costs per hour). A difference in hourly profit can stem from differences in hourly pricing (revenue) or hourly costs. Charging different rates per hour directly impacts hourly revenue, leading to different hourly profits. The other options are either less directly tied to hourly profit differences or rely on unstated, inconsistent comparisons.

Answer:

The owner of Sparkle seems to charge less per hour for cleaning services than the owner of Shine does.
