(a) Determine the company's sales mix.

Very simple:-

The sales mix:-

Bedroom division Dining room div. Total
Sales $500,000 750,000 1,250,000

MIX 2 : 3 = 5
MIX % = 40 % is to 60% = Total 100%

The question should also identify sales mix by revenue or by profitability, since it also gave you the contribution margin.

If by revenue, see the above answer.

If you profitability, then you need to use the contribution margin instead of using the sales amount.
