Greg plans to purchase a bicycle. bike a costs $270 and has an expected maintenance cost of $36 per year. bike b costs $360 and has an expected maintenance cost of $20 per year. which statement is true based on the average annual cost of each bike?
bike a is the better choice if greg plans on owning the bike for 5 years or 6 years.
bike b is the better choice if greg plans on owning the bike for 5 years or 6 years.
bike a is the better choice if greg plans on owning the bike for 5 years. bike b is the better choice if greg plans on owning the bike for 6 years.
bike b is the better choice if greg plans on owning the bike for 5 years. bike a is the better choice if greg plans on owning the bike for 6 years.

The Option 'Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years' is true.

Step-by-step explanation:

If x represents number of year and y represents the total cost  of the bike.

According to the question for bike A, total cost, y= 270+36x

And, for bike B, total cost, y= 360+20x

For 5 years price of A = 270 + 36 × 5=270 +180 = 450 dollar

For 5 years price of B= 360+ 20 × 5=360+100= 460 dollar

Thus, for 5 years price of A< price of B

⇒For 5 years Bike A is the better choice than Bike B.

For 6 years price of A = 270 + 36 × 6=270 +216 = 486 dollar

For 6 years price of B= 360+ 20 × 6=360+120= 480 dollar

Thus, for 6 years price of A> price of B

⇒For 6 years Bike B is the better choice than Bike A.

assuming you mean addition: addition and subtraction are reverse operations.
