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 $3780 write an equation to find the cost per bar

Answer 1

Answer:

Cost/bar = ((Cost after discount)+(discount))/(number of metal bars purchased.)

Step-by-step explanation:

Let's assume some variables to avoid being lengthy;

c = cost/bar.

n = number of bars purchased.

d = discount given

Cd = cost to pay after discount.

Ac = Actual cost, without discount

Now as we are given.that the individual is paying 3780 due to a peculiar discount as he had fulfilled the criteria to claim it by purchasing more than 500 bars; thus, the actual cost(without discount) would be:

Ac = Cd + d, obviously.

Now, That would be the cost of 525 bars, for one particular bar, we simply divide the total cost by 525(assume a scenario that includes candies, and the total cost is 100, and I purchased 50 candies, then the cost for each candy would be definitely 2, how? By dividing the cost with number of candies), as:

c = (Cd+d)/n
