question:A car dealership sells two models, A and B. Model A has a profit margin of 1,000 and model B has a profit margin of 500. Last year, the dealer sold 500 model As and 1,000 model Bs. This year the dealer wants to increase profit from last year by 20%. To do this the dealer has two options. Option 1 is to increase the profit margin on model A by 10% (to 1,100) and on model B by 10% (to 550). Option 2 is to increase the number of model As sold by 10% (to 550) and the number of model Bs sold by 10% (to 1,100). Which option is better and why?

answer:To determine which option is better, let's calculate the total profit for last year and then for each of the two options. Last year's total profit: Model A profit = 500 units * 1,000/unit = 500,000 Model B profit = 1,000 units * 500/unit = 500,000 Total profit = 500,000 + 500,000 = 1,000,000 The dealer wants to increase this profit by 20%, so the target profit for this year is 1,000,000 * 1.20 = 1,200,000. Now, let's calculate the total profit for each option: Option 1: Increase the profit margin on both models by 10% Model A profit = 500 units * 1,100/unit = 550,000 Model B profit = 1,000 units * 550/unit = 550,000 Total profit = 550,000 + 550,000 = 1,100,000 Option 2: Increase the number of units sold by 10% Model A profit = 550 units * 1,000/unit = 550,000 Model B profit = 1,100 units * 500/unit = 550,000 Total profit = 550,000 + 550,000 = 1,100,000 Both options result in a total profit of 1,100,000, which is a 10% increase over last year, not 20%. However, they are equally better than the current situation but do not meet the target profit of 1,200,000. Neither option is better than the other in terms of achieving the 20% increase, but if we had to choose, it could be based on other factors, such as feasibility, marketing strategy, or competition.

question:Since neither option alone results in a 20% increase in profit, can the dealer achieve a 20% increase in profit by combining both options 1 and 2 together?

answer:To determine if combining both options can achieve a 20% increase in profit, let's calculate the total profit if the dealer increases both the profit margin and the number of units sold. Model A profit = 550 units * 1,100/unit = 605,000 Model B profit = 1,100 units * 550/unit = 605,000 Total profit = 605,000 + 605,000 = 1,210,000 By combining both options, the dealer's total profit is now 1,210,000, which is more than the target profit of 1,200,000, representing a 21% increase over last year's profit. Therefore, the dealer can achieve the desired 20% increase in profit by combining both options and implementing a 10% increase in both profit margin and the number of units sold for both models.

question:Does the dealer achieve a profit increase of more than 20% by combining both options because the two 10% changes interact and its effect becomes compounded? That is, the increased profit margin is multiplied by the increased sales rather than the two effects being merely additive. Is that the case?

answer:The dealer achieves a profit increase of more than 20% by combining both options because the effects of the two 10% changes are multiplicative, not additive. When the dealer increases the profit margin by 10%, the profit per unit increases, and when the dealer also increases the number of units sold by 10%, the total profit is the product of these two increases. This means that the effect of the increased profit margin is multiplied by the effect of the increased sales, resulting in a compounded effect. In mathematical terms, if we have two independent 10% increases, the total effect would be (1 + 0.10) * (1 + 0.10) = 1.10 * 1.10 = 1.21, which is a 21% increase. This is why combining both options results in a total profit increase of more than 20%, rather than just the sum of the two individual increases (10% + 10% = 20%). The interaction between the two changes creates a compounding effect that amplifies the total increase in profit.
