Step-by-step explanation:
Equation 1:Using 'd' as per drink, and 't' as the total cost:
Golden Corral charges 11 dollars for the buffet. ( + 11 )
They also charge 1 dollar for each drink This could be represented by ' 1d' or 'd'.
So, the Golden Corral deal can be represented by:
t = d + 11
Equation 2:The Western Sizzlin restaurants charge 9 dollars for a buffet. ( + 9 )
They also charge 2 dollars for the drinks. This is represented by '2d'.
The Western Sizzlin deal can be represented by:
t = 2d + 9
Graphing the equations together, Golden Corral's line is less steeper then Western Sizzlin's line.
Therefore, Golden Corral is cheaper and should be the best deal compared to Western Sizziln'.
