Final answer:
To determine how much money you make per hour from walking the dog, multiply the 30-minute earnings by 2 because there are 60 minutes in an hour. The ratio in fractional form for the earnings per hour is 6% dollars to 1 hour.
Step-by-step explanation:
The question asks you to calculate how much money you make per hour if you currently earn 3% dollars when walking the dog for 30 minutes. To express this in a ratio in fractional form, you need to calculate the earnings per hour, considering that there are 60 minutes in an hour. If 30 minutes earns you 3% dollars, then 60 minutes, which is double the time, would earn you double the amount, hence 6% dollars per hour. The ratio of earnings per hour would be 6% to 1 hour.
Using the reference example, if your job pays $10 per hour and you receive a $2 raise, the percentage change in your pay is calculated as $2/$10 = 0.20 or 20%. Applying similar logic, but focused on the time ratio for the dog walking, we can deduce the money per hour for the provided scenario.
