Question 768729: a local zoo found that if the price of admission was $11, the attendance was about 1950 customers per day. when the price of admission was dropped to $7, attendance increased to about 2550 per day. write a linear equation for the attendance in terms of the price,p. (A=mp+b)

One way to do this is make a system of equations. Use a form, mp+b=A.
Two equations from your data pairs are:
m%2A11%2Bb=1950 and m%2A%2811-7%29%2Bb=2250, which is the system:
--------------------
highlight%2811m%2Bb=1950%29
highlight%284m%2Bb=2250%29
--------------------
Solve the equations for m and b any way you want; substitution, elimination, graphing.
