A local cinema found that if the price of admission was $16, the attendance was about 950 customers per day. When the price of admission was dropped to $5, attendance increased to about 1550 per day. Write a linear equation for the attendance in terms of the price, p. (A = mp+b)

A = -10*p + 2220

Step-by-step explanation:

To write a linear equation let define

A = attendance

m = slope of the line

b = intercept of the line

p = Price  of admision

let´s find m, using the two points (p,A)

point 1 = (13, 2050)

point 2 = (12, 2100)

m = (2100 – 2050)/(12-17) = -10

Replacing m in the equation  

A=-10p+b

To find b, let´s use point 1  

2050 = -10*17 + b

B = 2050  + 170

b = 2220

finally, the equation is

A = -10*p + 2220

b. x + 1

step-by-step explanation:

i'am smart

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
