Question

120 lb to 180 lb increase or decrease

Answer 1

We are asked to find out whether 120 lb to 180 lb is an increase or decrease​?

Since the final amount (180 lb) is greater than the initial amount (120 lb) the difference will be positive.

A positve difference indictes an increase.

$difference=180\: lb-120\: lb=60\: lb$

Therefore, the difference is positive (that is 60 lb) and it is an increase.
