Answer:
Density of propane = 17.8 g/L
Propane is more priced than gasoline
Explanation:
Given:
Temperature, T = 298 K
Pressure, P = 10 bar = 0.987 × 10 = 9.87 atm
now,
Molar mass of propane, M = 44.1 g/mol
From ideal gas law
⇒ PV = nRT
here,
n is the number of moles
R is the ideal gas constant = 0.0821 L.atm/mol.K
also,
Density, D = 
or
V = 
and,
nM = mass
thus,
V = 
substituting in the ideal gas relation
we have
P = 
or
D = 
or
D = 
or
D = 17.8 g/L
Now,
1 gallon = 3.78 Liter
Therefore,
5 gallon = 5 × 3.78 Liter = 18.9 Liter
Thus,
mass of 5 gallon propane = Volume × Density
= 18.9 Liter × 17.8 g/L
= 336.42 g
or
= 0.336 kg
also it is given that Price of 5 gallon propane i.e 0.336 kg = $30
Therefore,
Price per kg = 
= $89.28
and,
Mass of 5 gallons i.e 18.9 Liter gasoline = Density × Volume
= 0.692 g/cm³ × 18.9 Liter
also,
1 L = 1000 cm³
thus,
= 0.692 g/cm³ × 18.9 × 1000 cm³
= 13078.8 g
or
= 13.078 kg
Therefore,
Price per kg of gasoline = 
= $2.29
hence, propane is more priced than gasoline

Monopolistic competition refers to a market where there are a large of suppliers that offer differentiated products to a large number of consumers. The restaurant industry are the most common example of monopolistic competition.
The other options are wrong:
Sprint, AT&T, Verizon, and T-Mobile own a large portion of the U.S. cellular market share. OLIGOPOLISTIC MARKET (FEW SUPPLIERS AND MANY CONSUMERS)
Farmers grow navel oranges throughout the United States. PERFECT COMPETITION (MANY SUPPLIERS AND MANY CONSUMERS THAT SUPPLY SIMILAR PRODUCTS)
The local gas company owns all of the gas lines that supply natural gas and heating to the residents in the town of Madison, Wisconsin. MONOPOLY, ONLY ONE SUPPLIER AND MANY CONSUMERS
Answer:
Interpreting research findings
Explanation:
Answer:Decrease in supply.
Explanation: Supply is the amount of goods and services which an individual is willing and ready to purchase at a given price. The invention of a new technology which makes gasoline production less costly will lead to a decrease in price. Producers reduces supply when there's a decrease in price and increase supply when there's an increase in price. Also, the destruction of several oil fields means that there would be a reduction in the supply of oil in the economy. Since oil fields have been destroyed, it will have a negative effect on supply.
