Answer this question:A tank with a capacity of 8000 gallons is 3/4 full. Daxton empty's the tank by 40% of the total volume of water in the tank to water his vegetable farm. He then fills the tank with 30% of the volume of water remaining in the tank. Calculate the final volume of water in the tank.
The volume of water that is in the tank initially is 3 / 4 * 8000 = 6000 gallons. When Daxton empties 40% of the water, he pumps out 40 / 100 * 6000 = 2400 gallons of water. The total volume of water remaining in the tank is 6000 - 2400 = 3600 gallons. Daxton then fills the tank with 30 / 100 * 3600 = 1080 gallons of water. The final volume of water in the tank is 3600 + 1080 = 4680 gallons.
The answer is 4680.

Answer this question:A family just bought a newborn puppy that must eat a special type of dog food until it is 1 year old. The puppy needs to eat 2 ounces of this special dog food per day during the first 60 days of its life. After that, it needs to eat 4 ounces per day of the special food until it is old enough to eat regular dog food. If the special dog food is only sold in 5-pound bags, and there are 16 ounces in a pound, how many bags will the family need to buy to feed the puppy until it is old enough to eat regular dog food?
The puppy will consume 60 * 2 = 120 ounces of the special dog food in the first 60 days. This leaves 365 - 60 = 305 days where the puppy will consume 4 ounces of food per day, or 305 * 4 = 1220 ounces of the special food. Thus, the puppy requires a total of 120 + 1220 = 1340 ounces of food before it is 1 year old. Each 5 - pound bag contains 5 * 16 = 80 ounces of special dog food. Therefore, the puppy will need to eat 1340 / 80 = 16.75 bags of the special dog food, meaning the family will need to buy 17 bags.
The answer is 17.

Answer this question:Sabina is starting her first year of college that costs $30,000. She has saved $10,000 for her first year. She was awarded a grant that will cover 40% of the remainder of her tuition. How much will Sabina need to apply for to receive a loan that will cover her tuition?
The remainder of Sabina’s tuition bill comes to $30,000 - $10,000 = $20,000. The grant will cover $20,000 * 0.40 = $8,000 of her tuition. That means that Sabina will need to apply for a loan of $20,000 - $8,000 = $12,000 to pay for the rest of her tuition.
The answer is 12000.

Answer this question:Susie babysits every day for 3 hours a day at the rate of $10 per hour. She spent 3/10 of the money she earned from last week to buy a make-up set. She then spent 2/5 of her money on her skincare products. How much is left from her earnings last week, in dollars?
Susie earned $10 x 3 = $30 per day. Last week, she earned a total of $30 x 7 = $210. She spent $210 x 3 / 10 = $63 on make - up. While she spent $210 x 2 / 5 = $84 on her skincare products. Thus, she spent a total of $63 + $84 = $147 from her earnings. Therefore, Susie is left with $210 - $147 = $63 from her earnings last week.
The answer is 63.
