Answer :
The discount rate is calculated by dividing the amount of the discount by the list price, which in this case is 57% when rounded to two decimal places.
The question provided is asking us to find the discount rate given the amount of the discount and the net price. We are given that the amount of the discount is $12.54 and the net price (L - dL) is $9.46. In this context, L is the list price and d is the discount rate expressed as a decimal.
The list price (L) can be found by adding the discount to the net price: L = $9.46 + $12.54 = $22.00. To find the discount rate, we need to rearrange the given formula to d = $12.54 / $22.00, which when calculated, gives us the discount rate. After doing the calculation, we find that d = 0.57 or 57% when expressed as a percentage and rounded to two decimal places.
