Answer:
250 hamburgers were sold on Sunday
Step-by-step explanation:
Let there are x hamburgers and y cheeseburgers sold on Sunday.
ATQ,
x + y = 553 .....(1)
There were 53 more cheeseburgers sold than hamburgers.
y = 53 + x ....(2)
Put the value of y from equation (2) in equation (1).
x + (53 + x) = 553
2x+53 = 553
2x = 500
x = 250
Put the value of x in equation (2).
y = 53 + 250
y = 303
Hence, 250 hamburgers were sold on Sunday
