Chandler can eat a total of 23 apples and Lucy can eat a total of 19 apples per week. If the farmer only delivers 1 time per month, how many apples do they have to order for a month?
Chandler and Lucy can eat 23 + 19 = <<23+19=42>>42 apples per week.
Therefore, they have to order 42 x 4 = <<42*4=168>>168 apples for a month.
