PLEASE HELP! It's about inequalities

Part A: Write an inequality to represent the situation.

Part B: Solve the inequality. Show all of your work.

Part C: Interpret the solution in terms of the problem.

Answer 1

Answer:

Part A) 45-21 ≥ 4x

Part C) She could buy up to 8 notebooks

Step-by-step explanation:

She already spent $21 so you would need to subtract that from the total budget.  The sign would be greater than or equal to since that's the max amount.

45-21 ≥ 34

34≥4x

Divide both sides by 4 to cancel it out.  You would get 8.5 but since you can't buy half a notebook it would be 8.
