Karen purchased a prepaid phone card for $30. long distance calls cost 16 cents a minute using this card. karen used her card only once to make a long distance call. if the remaining credit on her card is $24.08, how many minutes did her last call last?

30-24.08=5.92, 5.92/.16=37 minutes

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
