Portland and hadley operate in the same industry. portland’s sales, variable costs, and fixed costs are $1,000,000, $700,000, and $100,000, respectively. hadley’s sales, variable costs, and fixed costs are $1,000,000, $400,000, and $400,000, respectively. if each company experiences an equal increase or decrease in sales, hadley’s income willa: go up twice as much as hadley’s, but go down only half as much as hadley’s. b: go up or down twice as much as hadley’s. c: go up or down by the same amount as hadley’s because both companies have equal net income. d: go up or down half as much as hadley’s.

The answer is: Portland's income will go D: Go up or down half as much as Hadley’s.

Explanation:

We can simulate different total sales movements:

Portland's sales

Current sales              20% increase                 20% decrease

$1,000,000                 $1,200,000                      $800,000

($700,000)                  ($840,000)                      ($560,000)

($100,000)                  ($100,000)                     ($100,000)                                            

$200,000                    $260,000 (+30%)            $140,000 (-30%)

Hadley's sales

Current sales              20% increase                 20% decrease

$1,000,000                 $1,200,000                      $800,000

($400,000)                  ($480,000)                      ($320,000)

($400,000)                 ($400,000)                     ($400,000)                                            

$200,000                    $320,000 (+60%)            $80,000 (-60%)

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"
