For every 5 books her students read, mrs. fenway gives them a free homework pass for 4 days. juan has accumulated homework passes for 16 days so far. what proportion would you write to find how many books juan has read?

20 Step-by-step explanation:

16 divided by 4 then multiply 5.

c-4 is the final answer! : )

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
