Memphis Company anticipates total sales for April, May, and June of $1,000,000, $1,100,000, and $1,150,000 respectively. Cash sales are normally 25% of total sales. Of the credit sales, 40% are collected in the same month as the sale, 55% are collected during the first month after the sale, and the remaining 5% are not collected. Compute the amount of cash received from credit sales during the month of May.

I know the answer is $742,500 but not sure how they came up with that?
