Which of the following increases when activity level increases? Total variable sost Total fixed cost Total mixed xost Both a and c. Which of the following is not a method used to analyzed mixed costs? Regression analysis Break-even analysis High-low method Scttergraph If total fixed costs for the month are $1.000and variable costs are 55 per units produced, calculate the total expected costs if a company expects to produce 400 units: below is the information for the number of t-shirts printed and total operating costs for a local store whose speciality is printing t-shirts for local sports terms. The prices shirts for soccer. basketball etc. teams. but the specialty is baseball jerseys which are printed in the May and June timeframe. Use this data, the scattergraph and the regression output to answer questions 4) through 6) below. The scattergraph represents the data for the year. This scattergraph indicates fixed costs of approximately $ per month. $6,000 $350 $3.600 $400 Using the high-low method, what is the equation for total operating com? Total Cost = $3, 362.50 + $10, 96 x (# of (-shifts printed) Total Cost = $2, 860.00 + $10, 96 x (# of t-shirts printed) Total Cost = $3, 362.50 4 + $7, 50 x (# of (-shins printed) Total Cost = $8, 853 4 + $0, 13 x (# of t-shirts printed)
