    The answer to your question is 2 toppings

    Step-by-step explanation:

    Data

    At Moss

    Pizza = $6.80 + $0.90 / topping

    At Lisa's

    Pizza = $7.30 + $0.65 / topping

    Process

    Write an equation for each Pizza shop

    At Moss Cost = 6.8 + 0.9t

    At Lisa's Cost = 7.30 + 0.65j

    Evaluate the equations changing the number of toppings until the cost be the same.

    Number of toppings Moss Lisa's

    1 6.8 + 0.9 (1) = 7.7 7.3 + 0.65 (1) = 7.95

    2 6.8 + 0.9 (2) = 8.6 7.3 + 0.65 (2) = 8.6

    Conclusions

    We need to add two toppings in order that the pizzas cost the same.
