Sam bought a soft drink for 3 dollars and 6 candy bars. He spent total of 21 dollors. How much did each candy bar oost?

To find out how much each candy bar cost, we can set up an equation based on the information given. Let's denote the cost of each candy bar as \( x \) dollars. From the information provided: 1. The cost of a soft drink is 3 dollars. 2. The total cost of 6 candy bars is 21 dollars. We can set up the equation as follows: \[ 3 + 6x = 21 \] Now, we can solve this equation to find the cost of each candy bar. Solve the equation by following steps: - step0: Solve for \(x\): \(3+6x=21\) - step1: Move the constant to the right side: \(6x=21-3\) - step2: Subtract the numbers: \(6x=18\) - step3: Divide both sides: \(\frac{6x}{6}=\frac{18}{6}\) - step4: Divide the numbers: \(x=3\) The cost of each candy bar is 3 dollars.
