Question

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?

Answer 1

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

Explanation:

Answer 2

A. Number of staplers.

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

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.
