The price of a stock increased by $3/day for six days, then decreased by $2/day for three days and then decreased by $5/day for two more days. If the final price of the stock was $39, what was its starting price?

$3 x 6 = $18 increase in the price of the stock.

[$2 x 3] + [$5 x 2] = $6 + $10 =$16 decrease in stock price.

Let the starting price =P

P + $18 - $16 = $39

P =$39 -$18 + $16 =$37 - The starting price of the stock.
