Question

$125 is to be divided among three restaurant servers.Angie made $30 more than Marie. Gwen, who went home sick, made $31 less than Marie. How much money should each server get?

Answer 1

 

 Try to do this one yourself

 

THINK: Which one do we know the LEAST about.... read it carefully....

 

Angie made $30 more than Marie <--- we know something about Angie

 Gwen made $31 less than Marie <---- we know something about Gwen

 

 We know NOTHING about Marie. THAT is where you assign the variable....

 Marie is X

 

 Now go back through and find the rest in terms of x:

   Angie = X+30

   Gwen X-31

 

What else are we told?  They total $125

 

 So angie + marie + gwen = 125

        x+30  + x + x-31 = 125

 

     3x - 1 = 125

  3x = 126

   x = 42

 

Marie earns $42

 Angie earns $72

 Gwen earns $11

The total is 125 so the answer is correct
