the article “Hong Kong demonstrators fashion bamboo bulwark” on page
A3 of the Tuesday, October 14th, Seattle Times.

fabric, how many square yards of material would they need?
A. 83 square yards
B. 110 square yards
D. 500 square yards
The construction worker was using 12-foot long bamboo poles, with
diameters of 2 inches. If the density of bamboo is about 20 lbs. per
cubic foot, how much did each pole weigh?
A. 5 lbs.
B. 10 lbs.
C. 20 lbs.
D. 60 lbs.
6. Much of the anger in Hong Kong is over the
rapid increase in the cost of living. Wealthy individuals from the
mainland have purchased apartments throughout the city, dramatically
increasing their prices. Studio apartments of just 177 square feet
are selling for $250,000. In the Seattle area, where typical
condominiums measure 935 square feet, the average price for a condo
is $325,000. Comparing the
price per square foot for residential housing in the two cities,
Hong Kong’s typical price per square foot is how many times greater
A. 80% as much
B. 380% as much

the article “Farmer’s ‘pumpkinstein’ creation grows into a monster
hit” on page A1 of the Monday, October 13th, Seattle
the U.S. about $7 billion in total will be spent on Halloween this
year, $2 billion of that just on candy. Approximately 60% of the
remaining money is spent on costumes. If the mean amount spent on
costumes is estimated to be $50 per person, how many costumes will
be purchased this year?
sold 5,500 pumpkins this year at $75 each. He is planning to switch
his pumpkin production solely to ‘pumpkinsteins’ next year and
expects to grow between 30,000 and 40,000. If he sells all of his
‘pumpkinsteins’ next year at the same price, what is the minimum
that his revenue from ‘pumpkinsteins’ will increase?
9. Dighera spent 4 years and $400,000 working
to refine his process. He expects to produce an average of 35,000
‘pumpkinsteins’ that he can sell each year. If Dighera expects to
make back his investment next year while keeping the price he
charges constant, then about how much does it cost to grow each
‘pumpkinstein’ he sells?
10. Dighera grows his ‘pumpkinsteins’ on a
40-acre farm and will potentially be able to produce 40,000 of them.
The ‘pumpkinsteins’ can only be produced from the first two pumpkins
from a pumpkin vine. If each vine takes up 30 square feet, what
percentage of his farm does he use to grow pumpkins? (1 acre =
43,560 sq. ft.)
