Answer:
4 dozens not sold
Step-by-step explanation:
total production = 40 dozen
half sold by noon = 40 × 50/100 = 20 dozens
remaining rolls after noon = 20 dozens
80% sold by closing time
20 × 80/100 = 16 dozens
total rolls sold at closing time = 20 + 16 = 36 dozens
remaining rolls after closing time
40 - 36 = 4 dozens
rolls not sold = 4 dozens
hope you get your answer
