Options:
a. October 9th
b. October 2nd
c. October 16th
d. October 23rd

Answer 1

To find out when Murphy paid his telephone bill after receiving it on September 18th, we add 21 days to that date, considering there are 30 days in September. The payment date falls on October 9th, option (a).

Step-by-step explanation:

When calculating the date Murphy paid his telephone bill, we consider three weeks after September 18th. A week has 7 days, so three weeks amount to 3 × 7 = 21 days. Adding 21 days to September 18th requires understanding the number of days in September, which are 30. This means that if we add the remaining 12 days of September to the 18th, it sums up to September 30th. Then we have 9 more days to add for October, which will be October 9th.

Therefore, by adding 21 days to September 18th, we find that Murphy paid his telephone bill on October 9th, which corresponds to option a.
