Answer:
He worked a total of 5 hours.
Explanation:
The first hour the man makes $35 dollars for the first hour then for the other hours he earns $23 dollars, right? So we start off with 35. 
 
35 = one hour. 
 
35 + 23 = 2 hours . = 58. 
 
35 + 23 + 23 = 3 hours. = 81. 
 
35 + 23 + 23 + 23 = 4 hours. = 104. 
 
35 + 23 + 23 + 23 + 23 = 5 hours. = 127. 
 
We were looking for if the man earned $127 dollars how many hours would be be working. 
 
 
He'd be working 5 hours. 
 
Hope this helps (:
