Question

a premature baby weighs only 3 pounds, 2 ounces at birth. After 16 days in intensive care, the baby has gained 22 ounces. Measure the babys age in days and weight in ounces. Assume the baby continues to gain weight at this same rate and a month has 30 days. What could be a possible algebraic expression?

Answer 1

clearly the baby has gained 22/16 oz/day.

So, starting with the birth weight of 50 oz, add that much for each day.

And what does the no. of days in a month have to do with anything?

Answer 2

50+22/16x
