Question

Yolanda, Kareem, and Jose served a total of 82 orders Monday at the school cafeteria. Kareem served 2 times as many orders as Jose. Yolanda served 6 fewer orders than Jose. How many orders did they each serve?

Answer 1

Yolanda served 13 times , Kareem served 38 times and Jose served 19 times.

Explanation:

No of orders served by Yolanda = x

No of orders served by Kareem = y

No of orders served by Jose = z

x + y + z = 82 ------------- (1)

y = 2z ------------ (2)

x = z - 6 ---------(3)

substituting (2) and (3) in (1) :-

z - 6 + 2z + z = 82

4z - 6 = 82

4z = 76

z = 19

y = 2(19)

y = 38

x = 19 - 6

x = 13
