Answer 1

B. Jacobs monthly bill shall be $48.75

Explanation:

On this specific mont, Jacob used 124.8 minutes.

Considering that every fraction of a minute is rounded off to the next minute,

Jacob used 125 minutes.

Each minute goes for $0.35

Now multiply total nomber of minutes by $0.35 rate

0.35 * 125 = 43.75

This is bill for the minutes used.

The bill for service is $5 per month.

To get the total bill, we add $5 to $43.75

Which gives us $48.75
