Question

The number of pieces of sausage needed by a pizza restaurant is given by the equation s 21n. In this equation, n is the number of pizzas the restaurant will make. How many pieces of sausage are needed to make 55 pizzas?

Answer 1

Assuming you meant S = 21n:

Replacing n with 55 pizzas yields us S = 21(55) and thus:

S = 1155.

You'll need 1155 pieces of sausage to make 55 pizzas.
