To calculate how much Johnny would be paid for 3.5 hours of work at the same rate, we must first determine his hourly rate from the information given. Since we know that Johnny was paid \($5.60 for 1 hour of work, we can conclude that his hourly rate is $\)5.60 per hour.
Now, to determine how much Johnny would make for 3.5 hours of work at the same rate, we multiply his hourly rate by the number of hours he would work.
Hourly rate = \($5.60
Number of hours worked = 3.5
Total pay = Hourly rate x Number of hours worked
Total pay = $\)5.60 x 3.5
To perform the multiplication:
Total pay = \($5.60 x 3 + $\)5.60 x 0.5
Total pay = \($16.80 + $\)2.80 (because 0.5 is half of an hour, so he would earn half of the hourly rate for that half-hour)
Total pay = \($19.60
So, at the same rate of pay, Johnny would earn $\)19.60 for 3.5 hours of work on the farm.
