Final answer:
Ginny earned more per hour for babysitting at $9.65 per hour compared to gardening at $8.25 per hour, making $1.40 more per hour from babysitting.
Step-by-step explanation:
To determine for which job Ginny earned more money per hour, we need to calculate the hourly rate for each job. For gardening, Ginny earned $49.50 for 6 hours of work. To find the hourly rate, we divide her total earnings by the number of hours worked:
$49.50 ÷ 6 hours = $8.25 per hour
For babysitting, Ginny earned $38.60 for 4 hours. Similarly, we calculate the hourly rate by dividing the total earnings by the hours worked:
$38.60 ÷ 4 hours = $9.65 per hour
Comparing the hourly rates, we can see that Ginny earned more per hour babysitting than gardening. To find out how much more she earned per hour from babysitting, we subtract the gardening hourly rate from the babysitting hourly rate:
$9.65 per hour - $8.25 per hour = $1.40 more per hour
Therefore, Ginny earned $1.40 more per hour from babysitting than from gardening.
