Answer
Find out the how many orders did they each serve .
To prove
Let us assume that the tony served be = x
As given
Laura,Ahmad,and Tony served a total of 94 orders Monday at the school cafeteria.
Ahmad served 3 times as many orders as Tony. Laura served 9 more orders than Tony.
Let us assume that the Ahmad served be = 3x
Let us assume that the Laura served be = 9 + x
Than the equation becomes
x + 3x + 9 + x = 94
5x = 94 - 9
5x = 85
x = 17
Tony served order be = 17
Ahmad served order be = 3 × 17
= 51
Laura served order be = 9 + x
= 9 + 17
= 26
Therefore the Tony served order is 17 , Ahmad served order is 51 and
Laura served order is 26 .
