Q. This equation shows how Bandit the puppy's weight varies with age.

\newline

p = 3a

\newline

The variable

a

represents Bandit's age in months, and the variable

p

represents Bandit's weight in pounds. How heavy was Bandit at

3

months old?

\newline

_____ pounds

Bandit's Age in Months: Bandit's age in months is given as $3$ . This $3$ is the value for the variable $a$ .
Substitute Value for $a$ : Substitute $3$ for $a$ in the equation $p = 3a$ . So, the equation becomes $p = 3 \times 3$ .
Calculate $p$ : Now, calculate the value of $p$ . So, $p = 9$ . But wait, I made a mistake, I forgot to multiply correctly.
