Answer:
For April, revenue was $90,000 and labor hours were 4x[(40x6)+(25x4)]. This is 90,000/1,360 = 66.18 dollars per hour of labor. For May, revenue was $80,000 and labor hours were 4x[(40x6)+(10x2)] This is 80,000/1,040 = 77 dollars per hour of labor a difference of $ 10.82per hour. The percentage change in productivity between April and May, then, is 3.95/44.12 = 0.1634935026x 100 = 16.35%
good luck ❤
