what equation do I use to find the price of the vegetarian special?

Question

On Thursday the restaurant collected $467 selling 21 veggie specials and 40 chicken specials

On Friday the restaurant collected $484 selling 28 veggie specials and 36 chicken specials

enter the cost in dollars of the veggie special

Answer 1

Lt C = price of the chicken specials and V= price of the veggie specials. Set up a system of 2 equations in 2 variables:

21V + 40C = 467

28V + 36C = 484 and solve using substitution
