Question

Heather, Carlos, and Ravi served a total of 139 orders Monday at the school cafeteria. Ravi served 4 times as many orders as Heather. Carlos served 5 fewer orders than Heather. How many orders did they each serve?

Answer 1

Let x = number of Meals served by Heather.

Then, Carlos served x - 5 meals and Ravi served 4x meals.

x + (x - 5) + 4x = 139

6x = 144

x = 24
