Analyse the original question further, we get producer’s selling price = distributor’s cost price. Also distributor’s profit percentage = 30%. If selling price is known then the cost price can be calculated using a formula that connects the cost price, the selling price and the profit percentage.
Identify the formula.
(a)$CP = \frac{SP \times100}{P\% + 100}$
(b)$CP = SP - P\%$
(c)$CP = SP \times (1 - \frac{P\%}{100})$
(d)$CP = SP \times \frac{P\%}{100}$
