Using proportions, it is found that there are 12 contestants in the event.
The complete question asks the number of contestants in the event.
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
In this problem, there are 180 hot dogs, and each contestant gets 15 hot dogs, hence the number of contestants in the event is given as follows:
180/15 = 12.
