Webster’s total cash collections

Question 7. Webster’s Discount Appliances expects sales of $10,000, $15,000, and $25,000 during April, May, and June (big sale in June). To build business, Webster let’s all customers buy on credit, and all do so. In the past, 20% of Webster’s Discount Appliances sales have been collected during the month of sale, 65% are collected the following month, and 15% the month after that. If this trend continues, what will be Webster’s total cash collections in the month of June?
