B. 108.05 because $200 for the old fridge with the added on $350 is $550 the to find the price of the new fridge you would take your percent and turn it into a decimal(divide by 100) and multiply the decimal by the original total $615 and you will get $43.05 you add $615 and $43.05 and you will get $658.05 minus that by the old fridges total and you will get $658.05-$550 which gives you $108.05
