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.
