Final answer:
Scott made a 110% gain on his investment after selling the car he imported from Japan. The unit price of bread per 100 grams is $1.10.
Step-by-step explanation:
To calculate the percentage gain Scott made on his investment, we would subtract the purchase price of the car from the selling price and then divide by the purchase price. After obtaining that number, we multiply by 100 to get the percentage.
Percentage gain = (($39,480 - $18,800) / $18,800) × 100
Percentage gain = ($20,680 / $18,800) × 100
Percentage gain = 1.1 × 100
Percentage gain = 110%
For the unit price per 100 grams of bread, we would divide the total price by the total grams and then multiply by 100 to get the price per 100 grams.
Unit price per 100 grams = ($3.30 / 300g) × 100
Unit price per 100 grams = $1.10 per 100 grams
