To find Kyle's average hourly earnings for the job, we can divide the total earnings by the total hours worked.
First, let's calculate the total earnings. We know that Kyle spent 3.2 hours completing the work, so we need to figure out how much he earned in total.
Ms. Davis hired Kyle to mow the grass, edge the lawn, clean up the leaves, and plant 2 flower beds. Let's assign a specific rate for each task:
- Mowing the grass: $10 per hour
- Edging the lawn: $12 per hour
- Cleaning up the leaves: $14 per hour
- Planting 2 flower beds: $20 per hour
To calculate the total earnings, we need to multiply the rate for each task by the time Kyle spent on that task and then sum them up:
Total earnings = (Rate for mowing the grass * time spent on mowing) + (Rate for edging the lawn * time spent on edging) + (Rate for cleaning up leaves * time spent on cleaning) + (Rate for planting flower beds * time spent on planting)
Total earnings = ($10 * time spent on mowing) + ($12 * time spent on edging) + ($14 * time spent on cleaning) + ($20 * time spent on planting)
Given that Kyle spent a total of 3.2 hours on the job, we need to find the time spent on each task. Since we don't have the exact breakdown of time for each task, we can assume that Kyle spent an equal amount of time on each task.
So, time spent on each task = total time spent / number of tasks = 3.2 hours / 4 tasks = 0.8 hours per task
Plugging in these values, we can calculate Kyle's total earnings:
Total earnings = ($10 * 0.8) + ($12 * 0.8) + ($14 * 0.8) + ($20 * 0.8)
Total earnings = $8 + $9.6 + $11.2 + $16
Total earnings = $44.8
Now, let's calculate Kyle's average hourly earnings:
Average hourly earnings = Total earnings / Total hours worked
Average hourly earnings = $44.8 / 3.2
Average hourly earnings ≈ $14
So, Kyle's average hourly earnings for the job is approximately $14.
