Final answer:
To find out how many tickets Aikira needs to become a black belt, we can subtract the points she has from the total points needed and then divide the result by 3.
Step-by-step explanation:
To determine how many tickets Aikira needs to become a black belt, we can use the equation:
t = (475 - 319) / 3
where t represents the number of tickets she needs. By subtracting the number of points she has already earned from the number of points needed for a black belt rating, we find the remaining points she needs. Then, by dividing this number by 3 (since she earns 3 points per ticket), we can find the number of tickets she needs.
In this case, the calculation would be:
t = (475 - 319) / 3 = 156 / 3 = 52
Therefore, Aikira needs 52 tickets to become a black belt.
