Step-by-step explanation:

Let x represent the amount spent on graphing calculator.

We have been given given that Sam has to spend $12 on paper and pencils. The total cost of graphing calculator, paper and pencils would be .

Since Sam can spend no more than $75 on school supplies, so the amount spent on school supplies should be less than or equal to 75.

We can represent this information in an inequality as:

Let us solve for x:

Therefore, Sam can spend a maximum amount of $63 on the graphing calculator.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
