Answer: A. $29.03
Step-by-step explanation:
10 boxes of paper at 6 lbs each = (10 * 6) = 60 lbs
36 boxes of pens at 12 oz each = (36 * 12) = 432 oz.

shipping charges : $ 12 for first 20 lbs, $ 10 for the next 30 lbs....so thats 50 lbs...leaving 37 lbs at 0.50 per lb = 37(0.50) = $ 18.50
for a total of : 12 + 10 + 18.50 = $ 40.50 <==
