After subtracting the number of lunches bought on Monday and Tuesday from the week's total, it is found that 450 students bought school lunch for the rest of the week.
The question is asking you to figure out how many students bought school lunch for the rest of the week after Monday and Tuesday's sales were considered. Using simple subtraction, deduct the number of lunches bought on Monday and Tuesday from the total for the week:
To calculate, we take the week total and minus Monday and Tuesday's sales (600 - 100 - 50) which gives us 450. Therefore, 450 students bought school lunch for the rest of the week.

6x - 5 is the total number of coins Nancy and Bill have.
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.
Variable: A variable is a symbol that doesn't have a fixed value.
Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
Coefficient: A coefficient is a number that is multiplied by a variable in an expression.
Given, Nancy has x coins
No. of coins Bill has = five coins less than 5 times of coins Nancy has
= 5x - 5
Total no. of coins Nancy and bill have = x + 5x -5
= 6x - 5
Hence, Nancy and Bill have total 6x - 5 coins.
