Required: 3. Using the high-low method, calculate the stores total fixed operating costs and variable operating cost per jersey. 4. Using the high-low method results, calculate the stores expected operating cost if it printed 425 jerseys. 5. Perform a least-squares regression analysis on Leslies data. 6. Using the regression output, create a linear equation (y = a + bx) for estimating Leslies operating costs. 7. Using the least-squares regression results, calculate the stores expected operating cost if it prints 620 jerseys.

Using the high-low method, calculate the stores total fixed operating costs and variable operating cost per jersey. (Do not round your intermediate calculations. Round your "Variable Cost" answer to 2 decimal places and "Fixed Cost" answer to the nearest whole number.)
