Hey there! The answer is 7x + 4y < 40
Let's first rearrange our data in a more structured way.
x represents a box of wings which has a cost of $7.00. Therefore the total cost of the boxes is 7x.
y represents a tray of nachos which has a cost of $4.00. Therefore the total cost of the trays is 4y.
The sum of the costs of trays and boxes, which is (7x + 4y) must be smaller than $40.
Now we can set up the inequality.

Answer:
Jason is 14 year old.
Step-by-step explanation:
Given: Joe, John and Jason are each a year apart in age.
Sum of their age is 39.
Lets assume the age of Joe be x
∴ Age of Jahn will be
And age of Jason will be
Now, putting up an equation for the sum of their age.
∴
Opening the parenthesis.
⇒
⇒
Subtracting both side by 3
⇒
Dividing both side by 3
⇒
∴
Hence, Joe is 12 year old.
Next subtituting the value of x to find age of Jason and John.
Jason=
∴Jason= 14 years.
John age=
∴ John Age= 13 years.
Hence, Jason is 14 year of age.
