EXERCISE 5-12 (30 MINUTES)

2. Scattergraph method (see the scattergraph on the following page): (Note: Students’ answers will vary due to the inherent imprecision of the quick-and-dirty method.) The line intersects the cost axis at about $1,200. The variable cost can be estimated as follows: Total cost at 100 scans (a point that falls on the line).... $3,000Less the fixed cost element... 1,200Variable cost element (total) ... $1,800 $1,800 ÷ 100 scans = $18 per scan. Therefore, the cost formula is: Y = $1,200 + $18X.
