First, we need to find the equation for Leon's profit

Using the table given

x₁ = 10 y₁ = 36

x₂= 12 y₂= 48

slope (m) = y₂-y₁ / x₂-x₁

= 48 - 36 /12-10

= 12/ 2

= 6

Substitute x = 10, y = 36 m = 6 into y=mx+ b and solve for b

36 = 6(10) + b

36 = 60 + b

subtract 60 from both-side of the equation

36 - 60 = b

-24 = b

To form the new equation

substitute m = 6 and b = -24 into y=mx + b

y = 6x - 24

comparing the two equations, the correct option is c
