show and explain
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
