I'm understanding up until the point were you get to 735=(3,500)(0.07)t and you get 245 i don't understand were you get 245 from i didn't get 245 when i multiplied or divided so can someone me understand were you get 245 from

Step-by-step explanation:(3500)(0.07)=250

In question said 3500 invested at 7% that's why you have to multiply

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

a
