Question

A membership at a swimming pool costs a flat fee of $100, plus $50 per person. If x stands for the number of people, then the membership cost is modeled by which equation?

y=150x
y=100+50+x
y=100x+50
y=50x+100

Answer 1

The correct answer is y=150x.For example, if I were to equal 300. Then that would mean two people would have bought the membership. So, X equals two.

Answer 2

y=50x+100

Explanation:

y=mx+b

100 is b because its a flat fee

The slope is 50 because it is dependent on x, the amount of people.
