Answer:
4 Weeks and 16 hours each
Step-by-step explanation:
Each of them have a formula, C being Cyrus and A being Adrian and W being weeks:
C=2w+8
A=4w
After working for 4 weeks, lets plug that in to the formulas
C=2(4)+8
C=16 hours
A=4(4)
A=16 hours
Both of them have worked for the same time and they each have the same number of hours.
