A baby weighs 18 pounds at her four month appointment. Six months later she weighs 24 pounds. By what percentage did the baby’s weight increase? Was this increase or decrease?

answer:

your answer is: c. 196 7/8 in^3.

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

open side up . . 1/50 . . 2%

closed side up . . 5/50 . . 10%

landed on side . . 44/50 . . 88%
