Answer:
1. 8/$12=21/$x then cross multiply.
2. 1/$1.5, we're looking for cost so $1 is more reasonable
3. $31.5
Step-by-step explanation:
12x 21/ 8 = 31.5
Answer is number 2
F(3)= (3-1)^2+ 3(3)=4+9= 13 so the first option is wrong
F(-2)= (-2-1)^2+ 3(-2)= 9-6=3 third options is wrong
F(-15)= (-15-1)^2 +3(-15)= 256-45= 211 fourth option is wrong

So there are 12 inches in a foot. What to do:
1) divide 200 by 12 which is roughly 16.6666 repeating
2) now we know that the average car length is at least 16 feet, but less than 17
3) What I do now, is I take 12 and multiply it by 16
12 x 16 = 192
4) 200-192 = 8
5) 16 feet and 8 inches is the answer
The answer is d
