  August 5,315     $ 69,419
  September 5,245     $ 69,025

Required:

1. Using the high–low method, estimate the cost formula for blood tests. (Round cost per unit answer to 2 decimal places.)

2. Using the cost formula you derived above, what blood test costs would you expect to be incurred during a month in which 4,410 blood tests are performed? (Round your intermediate calculations answer to 2 decimal places.)

Solution: 1
CALCULATION OF VARIABLE COST PER UNIT AND FIXED COST PER UNIT
Variable Cost per unit = High Level Total Cost - Low Level Total Cost / Change in Units Produced
High level month = February
Low Level Month = June
Change in Blood Test Cost                             = February Cost - June Cost = Difference
Change in Blood Test Cost                             = $                  70,530 - $              48,570 = $                   21,960
Divide By "/" By
Change in Blood Test Performed                             =                         5,400 -                     3,600 =                          1,800
=
Equals to Variable Cost Per unit = $                      12.20
Calculation of Fxed Cost
For the month of February 70530
Fixed Cost = Total Cost "-" Variable Cost
Fixed Cost =   $                  70,530 "-" $        65,880.00
(5,400 X $ 12.20)
Fixed Cost =   $                    4,650
Answer =
Variable Cost Per Blood Test = $ 12.20
Fixed Cost Element                          = 4,650
Y = a + bx
A =Fixed Cost = $                    4,650
bx = Variable Cost Per Unit X No. of Blood Test Performed $ 12.20 X Blood Test Performed
Solution: 2
Calcuation of Total cost for 4,410 blood test Performed
Variable Cost = 4,410 X $ 12.20 $                  53,802
Add: Fixed Cost $                    4,650
Total Cost $                  58,452
Answer = Total Cost = $ 58,452
