In problems 16-20, calculate the expected price in the year 2008 if you assume that there was a consistent 5% inflation rate and use the given 1988 price. answers should be rounded to the nearest penny. 16. median salary, $27,225 17. gallon of gas, $1.08 18. dozen eggs, $0.89 19. movie admission, $3.50 20. mcdonalds hamburger, $0.62

answer: a.   one is a factor of every whole number since every number is divisible by itself.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
