3. Scolt works on cars. He charges \( \$ 35 \) for each car plus \( \$ 7 \) per hour. How many hours did he work on Kylie's ca her bill was \( \$ 53 \) ?

Let's denote the number of hours Scolt worked on Kylie's car as \( h \). The total cost for Scolt's work on Kylie's car can be calculated as: \[ \text{Total Cost} = \$35 + \$7h \] Given that the total cost was \( \$53 \), we can set up the equation: \[ \$35 + \$7h = \$53 \] Now, we can solve this equation to find the number of hours Scolt worked on Kylie's car. Solve the equation by following steps: - step0: Solve for \(h\): \(35+7h=53\) - step1: Move the constant to the right side: \(7h=53-35\) - step2: Subtract the numbers: \(7h=18\) - step3: Divide both sides: \(\frac{7h}{7}=\frac{18}{7}\) - step4: Divide the numbers: \(h=\frac{18}{7}\) Scolt worked on Kylie's car for \( h = \frac{18}{7} \) hours, which is approximately 2.57 hours.
