Answer:
The equation that represents the amount Samuel earns per hour is "e = (total earned)/(total time worked)", on last weekend he earned 8.4 per hour.
Explanation:
Since Samuel worked a total of 2 and 1/4 hours it means that he worked:
hours worked = 2 + 1/4
hours worked = 8/4 + 1/4
hours worked = 9/4
He earned a total of 18.9 working that many hours. If we divide the total amount he earned by the number of worked hours we can find the total he earns per hour.
e = (total earned)/(total time worked)
e = 18.9/(9/4)
e = 18.9*(4/9)
e = 75.6/9
e = 8.4 per hour
The equation that represents the amount Samuel earns per hour is "e = (total earned)/(total time worked)", on last weekend he earned 8.4 per hour.
