Answer:

The system of equations will be:

p(x) = 0.9x + 6.80

m(x) = 0.65x + 7.30

Hence, option D is correct.

Step-by-step explanation:

The slope-intercept form of the linear equation

f(x) = mx+b

where

  • m is the rate of change or the slope
  • b is the y-intercept

Analyzing Papa's Pizzeria p function:

Given that A large pizza at Papa's Pizzeria cost $6.80 plus $0.90 for each topping.

  • Let p is the function of Papa's Pizzeria.

As the fixed cost or initial cost of Papa's Pizzeria is $6.80.

  • Thus, the y-intercept b = 6.80

As Papa's Pizzeria offers $0.90 for each topping.

  • Thus, the rate of change or slope m = 0.9

We know that the slope-intercept form of the linear equation

f(x) = mx + b

In this case, the function is m.

now substituting m = 0.9 and b = 6.80 in the slope-intercept form of linear equation

p(x) = 0.9x + 6.80

Thus, the equation that represents the Papa's Pizzeria topping and cost model.

p(x) = 0.9x + 6.80

Analyzing Papa's Pizzeria p function:

Given that a large cheese pizza at Mama's Pizza costs $7.30 plus $0.65 for each topping.

  • Let m is the function of Mam's Pizzeria.

As the fixed cost or initial cost of Mama's Pizza is $7.30.

  • Thus, the y-intercept b = 7.30

As Mama's Pizza offers $0.65 for each topping.

  • Thus, the rate of change or slope m = 0.65

We know that the slope-intercept form of the linear equation

f(x) = mx + b

In this case, the function is m.

now substituting m = 0.65 and b = 7.30 in the slope-intercept form of linear equation

m(x) = 0.65x + 7.30

Thus, the equation that represents the Mama's Pizza topping and cost model.

m(x) = 0.65x + 7.30

Conclusion:

The equation that represents the Papa's Pizzeria topping and cost model.

p(x) = 0.9x + 6.80

The equation that represents the Mama's Pizza topping and cost model.

m(x) = 0.65x + 7.30

Thus, the system of equations will be:

p(x) = 0.9x + 6.80

m(x) = 0.65x + 7.30

Hence, option D is correct.
