Given,
She orders 2 pizzas which will cost her $13.98 and if she 3 pizzas it will cost her $20.97.
Solution:
For 2 pizzas it will cost her $13.98.
For 1 pizza the cost will be
[tex]\begin{gathered} 1\text{ pizzas = }\frac{13.98}{2} \\ 1\text{ pizzas = \$ 6.99} \end{gathered}[/tex]
For 3 pizzas it will cost her $20.97.
[tex]\begin{gathered} 1\text{ pizzas =}\frac{20.97}{3} \\ 1\text{ pizzas = \$6.99} \end{gathered}[/tex]
Thus, Candice and Peter will pay the same price for each pizza.
