The swim club rents the municipal pool for a flat fee of $500 plus a charge of $75 per swimmer during
the summer months. Which of the following equations represents this scenario if the total cost to rent
the pool, y, is dependent upon the number of swimmers, x?

y=500+75x
y=500x+75
y=575x
y=500-75x

y=500+75x

Step-by-step

because it says plus a charge so you add

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
