To find out how many paints Lucia bought, we can set up the equation as follows:
Let \( x \) be the number of paints she bought.
The total amount she spent can be expressed as:
\[ 20 + 3x = 38 \]
Here, $20 is the cost of the canvas, and \( 3x \) is the total cost of the paints (where each paint costs $3).
Now, we can solve the equation for \( x \):
1. Subtract 20 from both sides:
\[ 3x = 38 - 20 \]
\[ 3x = 18 \]
2. Divide both sides by 3:
\[ x = \frac{18}{3} \]
\[ x = 6 \]
So, Lucia bought 6 paints.
Let \( x \) be the number of paints she bought.

Here, $20 is the cost of the canvas, and \( 3x \) is the total cost of the paints (where each paint costs $3).
Now, we can solve the equation for \( x \):
1. Subtract 20 from both sides:
\[ 3x = 38 - 20 \]
\[ 3x = 18 \]
2. Divide both sides by 3:
\[ x = \frac{18}{3} \]
\[ x = 6 \]
So, Lucia bought 6 paints.
