A gallon of gasoline carries with it about 1300 megaJoules of energy. If you pay $5 per gallon, how many megaJoules can you get for a dollar?
Since it's $5 for a gallon and 1 gallon contains 1300 megajoules of energy so for $1 dollar, I will have 1300/5=260 megajoules of energy. So the correct answer is 260megajoules of energy.

If “green” gasoline were sold for 20 cents per gallon more than “dirty” gasoline, would you buy it? How much of a premium per gallon do you think most people would pay?
Suppose that gasoline costs $3.55 per gallon. Your car gets 35 miles per gallon. How many gallons of gas do you need to drive 455 miles? How much will gasoline cost to drive 1000 miles? How many miles can you drive on 19 gallons of gas? How far can you drive on $15 worth of gas?
Pure gasoline has an energy density of 115,600 BTU per gallon, while ethanol has an energy density of 75,670 BTU per gallon. Gasoline costs $2.6 per gallon. What would the price of E85 (85% ethanol, 15% gasoline) have to be for its energy cost to be the same as that of pure gasoline? The price of E85 is determined to be_____
Suppose that you are interested in estimating the average number of miles per gallon of gasoline your car can get. You calculate the miles per gallon for each of the next thirteen times you fill the tank. Suppose that in truth, the values for your car are bell-shaped, with a mean of 20 miles per gallon and a standard deviation of 1. Find the possible sample means you are likely to get based on your sample of thirteen observations. Consider...
The Energy Information Administration reported that the mean retail price per gallon of regular grade gasoline was $3.51 . Suppose that the standard deviation was $0.10 and that the retail price per gallon has a bell-shaped distribution. (Hint: You must use the empirical rule for this problem. ) a. What percentage of regular grade gasoline sold between $3.31 and $3.71 per gallon (to 1 decimal)? b. What percentage of regular grade gasoline sold between $3.31 and $3.61 per gallon (to...
IP Energy from Gasoline Burning a gallon of gasoline releases 1.19 times 10^8 J of internal energy. Part A If a certain car requires 6.7 times 10^5 J of work to drive one mile, how much heat is given off to the atmosphere each mile, assuming the car gets 21.0 miles to the gallon? Q_rel = 104
Suppose one gallon of gasoline produces 1.1 X 10^8 J of energy, and this energy is sufficient to operate a car for 30 miles. An aspirin tablet has a mass of 290 mg. If the aspirin could be converted completely into thermal energy, how many miles would the car go on a single tablet?
IP Energy from Gasoline Burning a gallon of gasoline releases 1.1 9 × 108 J of internal energy.

If one gallon of gasoline contains about 2.0 g of lead, how much lead (in kg) is emitted into the atmosphere from a car that travels 10,000. miles a year and averages 25 miles per gallon of gasoline?
The U.S. Energy Administration reported that the mean price for a gallon of regular gasoline in the U.S, was $2.357. You are asked to test at a 06 level of significance whether the mean price for a gallon of gasoline in the Lower Atlantic states is different from the national mean. You sample 50 service stations in the Lowe determined the mean price for a gallon of regular gasoline was $2.343. The standard deviation for all stations in the lower...
