Question

the cost of endless chicken wings and sauce at restaurant x is $10. The cost of chicken wings at restaurant z is $0.50 per wing plus a one-time $1.50 charge for sauce. the total cost, c, of n chicken wings can be represented by a system of equations.
a.) write the system of equations that could be used to find out the cost of n chicken wings at each restaurant.
b.) graph the system of equations
c.) when will the total cost of the same number of chicken wings be the same at both restaurants? Explain.

Answer 1

Answer:

.27w+3=18

.27w=15

w=15/.27

w=55.5r

Sadly, there is no such number of wings. You can’t order fractional wings, only whole numbers of them. So you can either order 55 wings, paying $14.85 plus the $3 sauce charge, a total of $17.85, less than the $18 charge at restaurant W… or you can order 56 wings, paying $15.12 plus the $3 sauce charge, a total of $18.12, more than the $18 charge at restaurant W.

Even if you skip the sauce, you still end up picking either 66 (coming up short) or 67 wings (paying more)
