30) Compute the estimated costs for each of the following equations assuming the following costs for July:

Fixed manufacturing cost\$80,000

Variable cost per machine-hour6

Number of hours used2,000

In addition, state whether each is for a variable, fixed, or mixed cost.

a.Total estimated costs = intercept

b.Total estimated costs = constant

c.Total estimated costs = constant + (slope × cost driver)

d.Total estimated costs = slope coefficient × cost driver

In addition, state whether each is for a variable, fixed, or mixed cost.

31) Compute the estimated costs for each of the following equations, assuming the following costs for July:

Fixed manufacturing cost\$40,000

Variable cost per machine-hour6

Number of hours used1,000

In addition, state whether each is for a variable, fixed, or mixed cost.

a.Total estimated costs = intercept

b.Total estimated costs = constant

c.Total estimated costs = constant + (slope × cost driver)

d.Total estimated costs =  slope coefficient × cost driver

32) Write a cost estimating equation for each of the following conditions. Use y for estimated costs and X for activity of the cost driver.

a.Direct manufacturing labour is \$20 per hour.

b.Direct materials cost \$8.00 per cubic metre.

c.Utilities have a minimum charge of \$2,000 plus a charge of \$0.05 per kilowatt hour.

d.Factory supplies average \$10 per day plus \$1.00 for each machine-hour per day.

e.Total manufacturing amortization includes \$5,000 for straight-line plant amortization plus machinery amortization of \$100 for each day operated.
