Bottled water costs 075 euros per liter in Paris How much wo

Bottled water costs 0.75 euros per liter in Paris. How much would that cost in dollars per quart? (1 US$ = 0.78 Euros, 1 quart = 0.95 liters) Energy is what makes matter move or heat up. The international metric unit of energy is the joule. A 100-watt light bulb requires 100 joules per second. Your utility company charges 12 cents per kilowatt-hour of electricity. How much does it cost to keep a 100-watt light bulb on for a week? (1 kilowatt-hour = 3.6 million joules)

Solution

1 liter costs = 0.75 euros = 0.75/0.78 = $ 0.96

1 quart costs = $ 0.96* 0.95 (since 1 quart =0.95 liters)

= $ 0.912 (answer)
