Question

the average weight in pounds of a baby camel during its first month can be described by the equation below ( w = 12 + 3.7d ), where ( d ) is the number of days since born. what is the meaning of 3.7?

• the camel is this weight after 3.7 weeks
• the camels initial weight is 3.7 pounds
• the camel gains 3.7 pounds a day
• the camels weight after 3.7 days

Explanation:

The given equation $w = 12 + 3.7d$ is in the slope-intercept form $y = mx + b$, where $b$ is the initial value and $m$ is the rate of change. Here, $d$ is days since birth, $w$ is weight. The coefficient of $d$ (3.7) represents the daily weight gain.

Answer:

C. the camel gains 3.7 pounds a day
