Answer:
A. 30Lbs. 6 oz.
B. 27Lbs. 4oz.
Step-by-step explanation:
Considering that there are 16 ounces in one pound, you just have to add the ounces first so, 9+ 13= 22, subract that with 16 to get 6 ounces and carry the 16 ounces to 1 pound,the add the pounds. Now do that with the second equation.
8+12= 20
20-16= 4
15+11=26+1= 27
27 pounds and 4 ounces
30 pounds and 6 ounces
