Step-by-step explanation:
Area of a rectangle = length × width

B = 6
$40.50 10 boxes at 6lbs = 60lbs
36 boxes at 12 ounces = 432 ounces dived by 16(16 oz in a lbs)= 27 lbs
60 lbs plus 27 lbs = 87 lbs total weight
87lbs - 20lbs($12)= 67lbs - 30 lbs($10)= 37lbs x .50($.50 per pound)= $18.50
$12+$10+$18.50= $40.50
