Carla has 13 gallon's I quart of gas in her gas storage tank. She uses 38 quarts of gas to fill th tank of her snowmobile. How many quarts of gas remain in the storage tank?

Step 1: Convert gallons to quarts.  • Carla has 13 gallons and 1 quart.  • Since 1 gallon = 4 quarts, 13 gallons = 13 × 4 = 52 quarts.  • Total gas = 52 quarts + 1 quart = 53 quarts. Step 2: Subtract the quarts used.  • Carla used 38 quarts to fill her snowmobile.  • Remaining gas = 53 quarts − 38 quarts = 15 quarts. Answer: 15 quarts remain in the storage tank.
