Answer:
Elsa - 17 orders
Deon - 22 orders
Carlos - 68 orders
Step-by-step explanation:
You need to set variables and create system of equations first.
Elsa= e
Deon= d
Carlos = c
e+d+c=107
d=e+5
c=4e
Now you plug in the values into the equation x+y+z=116
e+(e+5)+(4e)=107
6e+5=107
6e=102
e=17
You plug in the value of x into the other equations.
e = 17
d= 17+5=22
c=4*(17)=68
Rearrange so it corresponds with days...
Elsa - 17 orders
Deon - 22 orders
Carlos - 68 orders
