Answer:

The short-run impact of each pricing strategy is as follows:
                                            Alternative 1                      Alternative 2
                              Reduce Price to $170     Maintain Price of $200
Gross profit                        $2,500,000               $3,200,000
Reduction in Gross Profit   $1,500,000                  $800,000
b. (2) maintain the same dollar price of $200, raise the real price in Brazil (to R$800 from R$680)to compensate for the devaluation, and experience a 20% drop in volume.
c. If HP maintains the same real price and same unit volume, the firm's gross profits will be $2,500,000.
Explanation:
a) Data and Calculations:
Exchange rate = R$3.40/US$
Current exports of printers per year to Brazil = 50,000
US unit price of printer in dollars = $200 
Brazil unit price of printer in R$ equivalent = R$680 ($200 * R$3.40)
Unit price of printer in R$ when reals is devalued = R$800 ($200 * R$4.00)
The reduced dollar price with devaluation, when real price is maintained = $170 (R$680/R$4.00)
Before Devaluation of Brazil's Real (R$):
Sales volume            50,000
Sales revenue $10,000,000 (50,000 * $200)
Direct costs         6,000,000 (50,000 * $120)
Gross profit       $4,000,000
                               Alternative 1                  Alternative 2
                        Reduce Price to $170     Maintain Price at $200
Sales volume                50,000                      40,000 (50,000 * 80%)
Sales revenue      $8,500,000               $8,000,000 ($200 * 40,000)
Direct costs            6,000,000                  4,800,000 ($120 * 40,000)
Gross profit         $2,500,000                $3,200,000 ($80 * 40,000)
Direct costs = $6m ($120 * 50,000)        = $4.8m ($120 * 40,000)
