Question

A building contractor buys 525 metal bars. Because he is buying more than 500 bars, the wholesaler gives him a discount of $420. The total price is $3,780. What is the cost of each metal bar?

Answer 1

The cost of each metal bar is $8.

Explanation:

We are given the following in the question:

Total number of bars bought = 525

Discount price = $420

Total price = $3,780

Let x be the unit cost of metal bars.

Thus, we can write the equation:

`525x - 420 = 3780`

Solving the equation, we get,

`525x - 420 = 3780\\525x = 4200\\\\\Rightarrow x = (4200)/(525)\\\\\Rightarrow x = 8`

Thus, cost of each metal bar is $8.
