PMBreakeven point

Hi Sir, I was trying to workout the below question but I did not understand how they have arrived in contribution per unit to find out the Breakeven point. Question : A company has a fixed cost of $1.3 million, variable costs are 55% of sales up to a sales level of $1.5 million, but a higher volumes of production and sales, the variable cost for incremental production units falls to 52% of sales. What is the breakeven point in sales revenue, to the nearest 1000?
