I'm doing a case study and I'm trying to find the break even point (in terms of tire sales)

Find Break even:
Goodyear 1991: Goodyear 1992 (prediction Sears):
Number of tires sold: 24,864,000 26,864,000
Average Retail Price per Tire: $150 $150
Gross Retail Sales: $3,729,600,000 $4,029,600,000
Dealer Margin: 0% ~40% (on how many tires?)
Net Retail Sales: $3,729,600,000 $3,729,600,000



in 1992, 2 million extra tires are sold on which there is a 40% dealer margin (because tires are sold through Sears)..


My question is how many tires have to be sold through Sears (with the 40% dealer margin) from the 26,864,000 to have the same Net retail as in 1991. So it's possible that for example 60% of the tires are sold without dealer margin and 40% with..
