Q. Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.\newlineA fashion photographer needs to hire a stylist to prepare his models. Zach charges $168\$168 for showing up, plus $70\$70 per hour. Troy charges $178\$178 plus $68\$68 per hour. The photographer realizes that, given the expected duration of his photo shoot, either stylist would cost him the same amount. What would the duration be? What would the cost be?\newlineIf the shoot lasted for _____ hours, either stylist would cost $\$_____.
  1. Define Variables: Let's define the variables.\newlineLet xx represent the number of hours the photo shoot lasts.\newlineLet yy represent the total cost for hiring either stylist.
  2. Write Zach's Equation: Write the equation for Zach's total cost.\newlineZach's total cost = (Hourly rate×Hours)+Initial charge(\text{Hourly rate} \times \text{Hours}) + \text{Initial charge}\newliney=(70×x)+168y = (70 \times x) + 168
  3. Write Troy's Equation: Write the equation for Troy's total cost.\newlineTroy's total cost = (Hourly rate×Hours)+Initial charge(\text{Hourly rate} \times \text{Hours}) + \text{Initial charge}\newliney=(68×x)+178y = (68 \times x) + 178
  4. Set Equations Equal: Set the two equations equal to each other to find the duration where the costs are the same.\newline(70×x)+168=(68×x)+178(70 \times x) + 168 = (68 \times x) + 178
  5. Solve for x: Solve for x by subtracting 68x68x from both sides and subtracting 168168 from both sides.\newline70x68x=17816870x - 68x = 178 - 168\newline2x=102x = 10
  6. Find Value of x: Divide both sides by 22 to find the value of xx.x=102x = \frac{10}{2}x=5x = 5
  7. Substitute xx into Equation: Substitute the value of xx back into either of the original equations to find the total cost yy.\newlineUsing Zach's equation:\newliney=(70×x)+168y = (70 \times x) + 168\newliney=(70×5)+168y = (70 \times 5) + 168\newliney=350+168y = 350 + 168\newliney=518y = 518
