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?

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:

Solving the equation, we get,

Thus, cost of each metal bar is $8.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
