Pete's Parlor sells 8 ounce containers of peanut butter for $4.48 and 10 ounce containers for $5.52. Write a linear equation to represent this problem

Question

It needs to be in two point slope form.

Answer 1

8 oz. $4.48

 

10 oz. $5.52

 

let's create points using weight for x and price for y:

 

(8, 4.48)

(10, 5.52)

 

solve for slope:

 

5.52 - 4.48     =    1.04    = $.52/oz.

  10 - 8                   2

 

y - 4.48 = .52(x - 8)

 

y = .52x - 4.16 + 4.48            -------> y = .52x + .32
