Okay, here we have this:
Considering the provided information, we are going to calculate the requested decrease and price of the next model, so we obtain the following:
Then according to the given information we will substitute in the following formulas:
Decrease in dollars = Current price * Decrease percentage
Decrease in dollars = $51000 * 13.8%
Decrease in dollars = $51000 * 0.138
Decrease in dollars = $7038
Price of the following model = Current price - Decrease in dollars
Price of the following model = $51000 - $7038
Price of the following model = $43962
Finally we obtain that the Decrease in dollars is $7038 and Price of the following model is $43962
