I am struggling on the allocated overhead was figured out from Chapter 7, Problem 17P in accounting for decision making and control (9th edition). This is the problem. I found the solution on Chegg, but I cannot figure out how the person came up with the allocated overhead of $888,889 and 611,111.

A) Prepare a typical monthly income statement for LiqVita and Dry after allocating the common fixed overhead costs of $1,500,000 per month to the two product lines based on the relative proportions of total variable costs generated by each product.
	LiqVita	Dry	Total
Revenue	$2,000,000	$1,575,000	$3,575,000
Variable Cost	1,200,000	825,000	2,025,000
Own Fixed Cost	90,000	110,000	200,000
Allocated Overhead	888,889	611,111	1,500,000.00
Net Income (loss)	($178,889)	$28,889
%Variable Cost	59%	41%
