The difference between what they paid for each uniform and what they got for each return is $1400.
An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Number of uniforms bought = 40
Total cost of uniforms = $3000
Now given returning cost = $40 per uniform
So, returning cost of all uniforms = $40*40
⇒ returning cost of all uniforms = $1600
Thus, the difference between what they paid for each uniform and what they got for each return = $3000- $1600
⇒ the difference between what they paid for each uniform and what they got for each return = $1400
Thus, the difference between what they paid for each uniform and what they got for each return is $1400.

The expressions (13 + 14) + 11 and 13 + (14 + 11) both demonstrate the associative property of addition. Regardless of how the meals are grouped in the parentheses, the total cost of the meals remains the same at $38.
The question is asking you to create mathematical expressions using parentheses to show the combined cost of three friends' restaurant meals, whose prices are $13, $14, and $11. We can do this by using the associative property of addition, which states that the way in which numbers are grouped when being added does not change the sum.
The first expression could be (13 + 14) + 11, where the meals costing $13 and $14 are grouped together first. The sum of these two meals is $27, so if we then add the $11 meal, we get a total of $38.
The second expression could be 13 + (14 + 11), where the meals costing $14 and $11 are grouped together first. The sum of these two meals is $25, so if we add the $13 meal, we still get a total of $38.
This shows the associative property of addition because regardless of how the meals are grouped in the parentheses, the total cost remains the same.
