  1. 1. correct
    2. p/6 = 7/8 ---> p= 42/8 = 5.25
    3. correct
    4. 521 miles in 14 hrs = 521/14 mph = 37.21 mph
    Your answer should have hit you as totally
    unreasonable.
    5. 33.6 gallons in six months --> 33.6/6 gal/mon
    = 5.6 gallons/month
    6. .81 euro = 1 dollar
    1 eur = 1/.81 dollars
    222 euros = 222(1/.81) dollars = $274.07
    7. perimeter is 20 cm, increased by a factor of 4
    since perimeter is a linear function, the new perimeter
    is 4(20) or 80 cm
    8. area is proportional to the square of a side
    increased by a factor of 3^2 or 9 times as big
    ---> 9(13) m^2 = 117 m^2
    9. can't tell, obviously base on some diagram
    10. original width = 30 , new width = 10
    factor = 1/3.
    How can you possibly have a factor of 3, your choice, if the width decreased ??
    11. YEAHHH, YOU GOT ONE RIGHT
    12. 30/15 = 2 and 45/15 = 3
    so 2 by 3 , which is the first choice
    13. YEHHH, ANOTHER ONE RIGHT

    4 right out of 13 !!!
    --- by just guessing you would have 4 correct.
