-
If the controller uses regression analysis to estimate costs, the cost equation for electricity costs is:

• A) Electricity Costs = $1,425.18 + ($12.00 × Machine hours).
• B) Electricity Costs = $3,726.88 + ($1,682.82 × Machine hours).
• C) Electricity Costs = $1,682.82 + ($0.49 × Machine hours).
• D) Electricity Costs = $3,726.88 + ($5.77 × Machine hours).
