Answer:
Following are the required equations
[tex]x +y=84[/tex]
[tex]6x +5y=440[/tex]
Step-by-step explanation:
Let x boxes of pecans and y boxes of peanuts sold.
Total no of boxes sold = 84
[tex]\implies x +y=84[/tex]
Cost of one box of pecan =$6
So, cost of x boxes of pecans =$6x
Cost of one box of peanuts = $5
So, cost of y boxes of peanuts =$5y
Total sales = $440
[tex]\implies 6x +5y=440[/tex]
