To find the unit cost for each company, we need to calculate the cost per hour for each company.
For Cell City, we are given that 2.5 hours cost $8. To find the cost per hour, we divide the total cost by the number of hours:
Cost per hour for Cell City = $8 / 2.5 hours = $3.20 per hour
For Smart Mobile, we are given that 1/2 hour costs $1.75. To find the cost per hour, we need to convert 1/2 hour to a whole hour. Since there are 2 half-hours in 1 hour, we multiply the cost by 2:
Cost per hour for Smart Mobile = $1.75 * 2 = $3.50 per hour
So the unit cost for each company is:
Cell City: $3.20 per hour
Smart Mobile: $3.50 per hour
