Answer:
Hence, in this case, it is concluded that the correct answer is "N = 618 - n x 7"
Step-by-step explanation:
Considering the situation described above, the explicit formula that shows the number of ice cream tickets remaining at the end of the day, after n number of days is "N = 618 - n x 7."
This is based on the idea that each day of the ice cream ticket is defined as 7 tickets taken.
Thus the ticket listing for each day is described as
Day 1. 618 - 7 OR 618 - 1 × 7;
Day 2. 618 - 14 OR. 618 - 2 × 7;
Day 3. 618 - 21 OR 618 - 3 × 7;
Therefore, from this illustration above, the formula needed is: "N = 618 - n x 7."
