A furniture store sells only two models of desks, model A and model B.

The selling price of model A is 120 dollars, which is 30 percent of the selling price of model B. Ok, so what is the selling price of model B?

If the furniture store sells 2,000 desks, 3/4 of which are model B, what is the furniture store's total revenue from the sale of desks? Ok, so how many of each model are sold?

I can let x be the total revenue from the sale of desks.

Can someone break this problem down one step at a time? Providing the equation set up is ok but does not clarify the problem at hand.
