Answer:

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.
