Need help finding the linear equation

Question

A local water park found that if the price of admission was $16 the attendance was about 2850 customers per week. When the price of admission was dropped to $10 attendance increased to about 3100 per week. Write a linear equation for the attendance in terms of the price (a=no+b)

Answer 1

changed the variables in the line equation to be slightly more suggestive as

a=n*p+b

where a=attendance and p=price of admission.

The line is of the form

a=-125/3*p+10550/3
