Answer:
2.5 hours
Step-by-step explanation:
70x+25=50x+75
step 1 subtract 25 from each side
25-25 cancels out
75-25=50
Now we have
70x=50x+75
step 2 subtract 50 from each side
70x-50x=20x
50x-50x cancels out
now we have
20x=50
step 3 divide each side by 20
20/20 cancels out
50/20=5/2 or 2.5
so we can conclude that it will take 2.5 hours of service for the services to cost the same
