LiRa [457]

Company charges 8 cents per call and the call in question is 3 minutes. Cost is;

= 3 * 8

= 24 cents

Company however stipulates that a call is 8 cents per minute or a 50​-cent minimum charge per completed​ call, whichever is greater.

borishaifa [10]
C. About 4 hours. When you add the numbers together, you get

2 1/8 + 2 1/4 = 35/8 = 4 3/8 = 4.375

Since the answer is not greater than 4.5, you round down to 4. If the answer was greater than 4.5, you would have rounded up to 5.
