Answer:
7x + 4y < 40
Step-by-step explanation:
each box of wings cost $7 and he buys x boxes, so
cost of wings = 7x
Now,
each tray of nachos is $4 and he buys y trays, so
cost of nachos = 4y
His budget limit is 40 dollars, so his total cost must be LESS THAN 40, thus we can write the inequality shown below:
7x + 4y < 40
