Explanation:

Step1: Set the function equal to zero

Set $m = 0$ in the equation $m=50 - 1.25w$. So, $0 = 50-1.25w$.

Step2: Solve for $w$

Add $1.25w$ to both sides of the equation: $1.25w=50$. Then divide both sides by $1.25$: $w=\frac{50}{1.25}=40$.

Step3: Interpret the result

The zero of the function means when $w = 40$, Moesha and Keyon have spent all their $50$ dollars on mailing wedding - invitations.

Answer:

The zero of the function is $w = 40$. This represents that after mailing 40 wedding invitations, Moesha and Keyon will have $0$ dollars left.
