Answer:
The cost of each metal bar is $8.
Step-by-step 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:
[tex]525x - 420 = 3780[/tex]
Solving the equation, we get,
[tex]525x - 420 = 3780\\525x = 4200\\\\\Rightarrow x = \dfrac{4200}{525}\\\\\Rightarrow x = 8[/tex]
Thus, cost of each metal bar is $8.
