If 2 1/2 pounds of bananas cost 1.89 what is the cost per pound?

Number nine is f(x)= 40x : ) hoped i ya

So we can turn the fraction into a decimal to make it easier

2.5 lbs (pounds)

since the bananas cost $1.89, we need to divide it with 2.5

1.89/2.5

=0.756

the answer would be $0.76

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
