The following data have been collected for four different cost items. Cost Item Cost at 100 units Cost at 140 units W $8,000 $10,560 X $5,000 $ 5,000 Y $6,500 $ 9,100 Z $6,700 $ 8,580 Which of the following classifications of these cost items by cost behavior is correct? Cost W Cost X Cost Y Cost Z A) variable fixed mixed variable B) mixed fixed variable mixed C) variable fixed variable variable D) mixed fixed mixed mixed

i'ts proportional. if the inflation rate is 12% for example, the cpi will be 12% less.

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
