Car “a” cost $43,000 and gets 48 miles per gallon, while car “b” cost $24,000 and gets 23 miles per gallon. assume you drive 12,000 miles per year and gas cost $2.42 per gallon. how many years will it take for car “a’s” better fuel economy to outweigh its higher initial cost?

The annual difference in gas cost is

... 12000(1/23 -1/48)×$2.42 ≈ $657.61

So, it will take (43,000 -24,000)/657.61 years ≈ 28.9 years for the better fuel economy to outweigh the initial cost difference.

_____

With the units where you can see them, the gas cost computation is ...

step-by-step explanation:

mean or average is 40.6

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
