350 hamburgers were sold on Tuesday.
Step-by-step explanation:
Given,
Number of hamburgers and cheeseburgers sold = 774
Let,
Number of hamburgers sold = x
Number of cheeseburgers sold = y
According to given statement;
x+y=774 Eqn 1
y = x+74 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
Dividing both sides by 2
350 hamburgers were sold on Tuesday.
