Mr. Khans is buying staplers for his office. Each stapler costs $16.99. Part A: What does his final total cost depend upon? Part B: In this scenario, what is the input? What is the output?

his cost depends on how many staplers he gets and the input is how much each stapler cost and output is how much he has to spend

A. Number of staplers.

B. Input is number of staplers and output is total cost.

Step-by-step explanation:

Part A : Let he bought x staplers,

∵ The cost of each stapler = $ 16.99

So, the cost of x staplers in dollars (say y) = price of each staplers * number of staplers

⇒ y = 16.99x

Which is the required equation that shows the given scenario,

∵ y ∝ x,

I. e. his final cost would depend upon the number of staplers.

Part B:

∵ in the equation y = 16.99x

x = input value, y = output value,

Thus, in this scenery, input is the number of staplers and output is total cost.
