Question

3. Boynton Beach recreation center has collected a total of 510 donated tickets for free ice

cones. Beginning on the second day of summer vacation, the recreation center randomly
selects 9 children to each receive one of the free ice cream tickets. Assuming the
recreation center continues this pattern of giving away tickets to 9 children each day,
which explicit formula shows the
number of ice cone tickets remaining at the end of the
day, after n number of days?
a.=510-9n
B.=510+9(n-1)
C.510-9(n-1)
D.9(n-1)-510

Answer 1

Hence, in this case, it is concluded that the correct answer is "N = 618 - n x 7"

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."
