To determine John’s hourly rate, solve the equation \(3.5x = 49\).

**Steps:**
1. Divide both sides by 3.5:
\(x = \frac{49}{3.5}\).
2. Simplify the division:
\(3.5 \times 14 = 49\), so \(x = 14\).

Verification:
\(3.5 \times 14 = 49\) (correct).

Options:
- **A ($1.40)** is too low (3.5 × 1.40 = $4.90).
- **B ($14.00)** matches the calculation.
- **C ($45.50)** and **D ($171.50)** are too high.

**Answer: B**		 B

GPT-4o To determine John’s hourly rate, we need to solve the equation 3.5x = 49.

Step 1: Divide both sides of the equation by 3.5 to isolate x.

\[ x = \frac{49}{3.5} \]

Step 2: Perform the division.

\[ x = 14 \]

Therefore, John’s hourly rate is $14.00.

To find the hourly rate x, divide both sides of the equation 3.5x = 49 by 3.5. x = 49 / 3.5 = 14. So the answer is B.		 B
minimax To find John's hourly rate, we need to solve the equation 3.5x = 49 for x, where x represents the hourly rate.

Divide both sides of the equation by 3.5 to isolate x:

x = 49 / 3.5

Now, calculate the value of x:

x = 14

Therefore, John's hourly rate would be $14.00.

The correct answer is B. $14.00.		 B
kimi To find John's hourly rate, we need to solve the equation for x, where x represents the hourly rate.

The equation is:
3.5x = 49

To solve for x, divide both sides of the equation by 3.5:
x = 49 / 3.5

Now, let's do the calculation:
x = 14

So, John's hourly rate would be $14.00.

Answer: B. $14.00		 B

zhipu To find John's hourly rate, we need to solve the equation \( 3.5x = 49 \) for \( x \).

First, divide both sides of the equation by 3.5:

\[ x = \frac{49}{3.5} \]

To perform the division:

\[ \frac{49}{3.5} = \frac{49 \times 2}{3.5 \times 2} = \frac{98}{7} = 14 \]

So, John's hourly rate is \( $14.00 \).

Therefore, the correct answer is:

B. $14.00		 B

deepseekv3 To determine John’s hourly rate, we can solve the equation:

\[ 3.5x = 49 \]

Where \( x \) is the hourly rate in dollars. To find \( x \), divide both sides of the equation by 3.5:

\[ x = \frac{49}{3.5} \]

\[ x = 14 \]

Therefore, John’s hourly rate is **$14.00**.

The correct answer is **B. $14.00**.		 B
