Pay for 8hrs = 8d
Pay for the additional 4hrs = 4c
Total Pay = 8d+4c
Total hours = 12

Average hourly = (8d+4c)/12 = (2d + c)/3

Aabhash777 · Answer

Pay for 8 hours = 8d
Pay for remaining 4 hours = 4c

Total Pay = 8d + 4c = 4(2d+c)

Total Hours = 12

Average Pay = 4(2d+c) / 12 = (2d+c) / 3
Answer A

SSPatil · Answer

We are given:
 
 A worker is paid  d dollars/hour  for the first  8 hours . 
 For the next hours, she is paid  c dollars/hour . 
 She works  12 hours total  in one day.

Step 1: Calculate total earnings
 
 First 8 hours: 8×d=8d 
 Next 4 hours (12 - 8): 4×c=4c 
 Total earnings = 8d+4c

Step 2: Calculate average hourly wage
 
 Total hours = 12  
Average hourly wage= (8d+4c)/12
Simplify:
=4(2d+c)/12 = (2d+c)/3

Correct Answer:  A. (2d + c)/3

Dereno · Answer

Per hour charge = d dollars/ hour.

For 8 hours = 8d dollars.

For hours after the 8 hours , we are paid c dollars per hour.

4 hours (12-8) extra is the worked hours.

Charge = 4*c dollars.

Total charge = (8d+4c) dollars

Average hourly rate = (8d+4c) /12 =  (2d+c)/3

Option A

A worker is paid d dollars an hour for the first 8 hours she works in
