Let's denote the number of vases Felicity has as \( v \) and the number of bowls as \( b \). We are given two key pieces of information:
- The total number of pottery pieces (vases and bowls) is 30.
- The total sales from these pieces amount to $477.
From these pieces of information, we can establish the following system of equations:
-
The first equation represents the total number of pieces: \[ v + b = 30 \]
-
The second equation represents the total sales from vases and bowls: \[ 21v + 12.5b = 477 \]
Now, we have a system of equations: \[ \begin{align*}
- & \quad v + b = 30 \
- & \quad 21v + 12.5b = 477 \end{align*} \]
You can solve this system of equations using substitution or elimination methods to find the values of \( v \) and \( b \). Would you like me to show you how to solve this system?
