To find the value of \( v \), we can set up an equation based on the information provided in the problem.
Brett put 3 flower pots and \( v \) vases in each bin. Since he filled 5 bins and used a total of 25 containers, we can express this mathematically as follows:
\[ 5 \times (3 + v) = 25 \]
Now, let's simplify the left side:
\[ 15 + 5v = 25 \]
Next, we can isolate \( 5v \) by subtracting 15 from both sides:
\[ 5v = 25 - 15 \] \[ 5v = 10 \]
Now, divide both sides by 5 to solve for \( v \):
\[ v = \frac{10}{5} \] \[ v = 2 \]
So, the value of \( v \) is \( 2 \). This means there are 2 vases in each bin.
