Question

Suppose a baby weighed 8 pounds at birth and gained about 1.2 pounds each month during the first year of life to the nearest pound approximately what was the weight of the baby after the seventh month

Answer 1

Multiply the gain per month by the number of months:

1.2 x 7 = 8.4 pounds.

Add to the birth weight:

8 + 8.4 = 16.4 pounds.

To the nearest pound = 16 pounds.
