If 1 lb = 16 oz, then 3 lb and 5 oz = 3 * 16 + 5 = 48 + 5 = 53 oz
Kitten weighed 5 oz at birth, so to find rate of change we need to substract it from the final weight: 53 - 5 = 48 oz
To find out how many oz the kitten grew per month, we need to divide the result by 6:
48 ÷ 6 = 8
Answer: Rate of change is 8 oz per month.
