Answer:
They sold 16 French fries.
Step-by-step explanation:
Let x represent the number of large burgers that they sold on that day.
Let y represent the number of French fries that they sold on that day.
fast food sells large burgers for five dollars each and french fries for three dollars each that day and their total sales was $98.It means that
5x + 3y = 98 - - - - - - - - - - - - - -1
they sold six more french fries than burgers. It means that
y = x + 6
Substituting y = x+ 6 into equation 1, it becomes
5x + 3(x + 6) = 98
5x + 3x + 18 = 98
8x = 98 - 18 = 80
x = 80/8 = 10
y = x + 6 = 10 + 6
y = 16
775-550 = 225 for an extra 15 guests
225/15= 15$ per person
