Have two ways: 1. Reflects with respect x-axis and later with respect y-axis.
2. The opposite: first with respect y-axis and later with respect x-axis.
B and D are correct.

Answer:
Cost to buy and run the first car for 5 years=$24000
Cost to buy and run the second car for 5 years=$26000
I think we should buy the first car, because It is cheaper to buy and maintain
Step-by-step explanation:
first car:
Cost $18000 to buy
Cost $100 to maintain each month
5years =5 x 12=60months
Cost to maintain for 60months=100x60=$6000
First car cost to buy and run over the 5 year period=18000+6000=$24000
Second car:
It cost $22400 to buy
Cost $60 to maintain each month
5years=60months
Cost to maintain for 60months is 60 x 60=$3600
Cost to buy and run over the second car for 5years is 22400+3600=$26000
(4/5)(1/2)=4/10=2/5

Hmm
that is a true statement, the product of any 2 mixed numbers between 4 and 5, will be between 16 and 25
we can show that it is true by testing the bounds
if the number is 4 and the other is 4, then it is 16
we aren't allowed to do 4 since it isn't mixed and it equals 4
that is the lower bbound
if the numbes 5 and 5 are used, then it is 25
we arene't allowed to use 5 since it isn't mixed and it equals 5
so the product of any 2 numbers between 4 and 5 will be between 16 and 25
so pick any random one
4 and 3/4 times 4 and 5/323
