Question

Your family goes to a souther-style restaurant for dinner. There are 6 people in your family. Some order the chicken dinner for 14$ and some order the steak for 17$. If the total bill was $99, how many people ordered each dinner?

Answer 1

1 person ordered chicken dinner and 5 persons steak.

Explanation:

Let the

Number of people who ordered chicken dinner = x

Number of people who ordered steak = y

Given that there are 6 people in your family and the total bill was $99. Also, cost of chicken dinner is 14$ and cost of the steak is 17$

Then,

x + y = 6 ----- Equation 1

14x + 17y = 99 ----- Equation 2

y = 6 - x

14x + 17(6 - x) = 99

14x - 17x + 102 = 99

-3x = 99 - 102

-3x = -3

x = 1

y = 6 - 1

y = 5

Therefore, 1 person ordered chicken dinner and 5 persons steak.
