Answer:
The budgeted sales are missing, so I looked for them. I found the following question, hopefully it will be similar:
Month Sales
April $300,000
May $320,000
June $370,000
Schedule of expected collections
For the month of June, 202x
Cash sales during June = $370,000 x 40% = $148,000
Collection from June's credit sales = $222,000 x 20% = $44,400
Collection from May's credit sales = $192,000 x 50% = $96,000
Collection from April's credit sales = $180,000 x 26% = $46,800
Total cash collections during June = $335,200
