Answer: The weight of mail at noon is 104 pounds.
Step-by-step explanation:
Given that , At a post office, the weight of the mail at 10.00 A.M was 80 pounds.
Two hours later, the weight of the mail had increased by 30%.
Since , time after 2 hours of 10 A.M would be 12 P.M which is known as noon.
Mathematically , the weight of the mail at noon = (Weight at 10 AM) +30% of (Weight at 10 AM)
= 80 + 0.30(80) pounds
= 80 (1+0.30) pounds
= 80 (1.30) pounds
= 104 pounds
Hence, the weight of mail at noon is 104 pounds.
