Answer:

20 Plates

Explanation:

Given that :

Sally's kitchen :

Setup cost = $60

Cost per plate = $12

Jimmy's BBQ :

Setup cost = $100

Cost per plate = $10

Let number of plates = x

Equate both and solve for x :

Sally's kitchen = Jimmy's BBQ

60 + 12x = 100 + 10x

12x - 10x = 100 - 60

2x = 40

x = 40/2

x = 20

20 plates
