To find out how much money Tommy's class collected, we need to solve the equation:
\[ 2(x + 3.00) = 34.00 \]
First, divide both sides by 2:
\[ x + 3.00 = \frac{34.00}{2} \]
This simplifies to:
\[ x + 3.00 = 17.00 \]
Next, subtract $3.00 from both sides:
\[ x = 17.00 - 3.00 \]
This gives us:
\[ x = 14.00 \]
So, Tommy's class collected **$14.00**.
The correct answer is **A. $14.00**.
\[ 2(x + 3.00) = 34.00 \]
First, divide both sides by 2:
\[ x + 3.00 = \frac{34.00}{2} \]
This simplifies to:
\[ x + 3.00 = 17.00 \]
Next, subtract $3.00 from both sides:
\[ x = 17.00 - 3.00 \]
This gives us:
\[ x = 14.00 \]
So, Tommy's class collected **$14.00**.
The correct answer is **A. $14.00**.
