Aikira needs 475 points to receive a black belt rating in class. She has already earned
319 points and gets 3 points for each ticket she receives. How many tickets (t) does she
need to become a black belt?

52

Step-by-step explanation:

since the number of point she need is 475 and the number of points she has already is 319

therefore the number of point she now needs to gain in order to get black belt rating is 475-319=156

if 1 ticket = 3points

then 156/3=52

therefore the number of tickets she needs is 52

i think it would be 42cm
