I'll mark ur answer as brainlist. 4) A baby bear is born and weighs only 12 ounces. The baby rebounds to weigh 57 pounds after one year. What was the bear's growth rate per month? Per week? explain ur answer, pls.

75 oz / 1 month,    17.308 oz / 1 week

Step-by-step explanation:

baby = 12 oz

1 year = 57 lbs

1 lb = 16 oz

difference between 1 year and birth = ( 57 lbs ) * 16 - ( 12 ) = 900 oz

growth rate = 900 oz / 1 year   -->   75 oz / 1 month   -->   17.308 oz / 1 week
