<PRE><B>Question 658690</B>

Find the cost of, in cents, of 8 books if 3 books of the same kind cost D dollar
(1) 8D divided by three
(2)3 divided by 800D
(3)3 divided by 8D
(4) 800D divided by 3
(5) 108D divided by 3


If 3 books cost a total of D dollars, then 3 books cost D(100), or 100D cents


With cost of 8 books being C, we can say that:


{{{3/8 = 100D/C}}}


3C = 800D ------ Cross-multiplying


C, or cost of 8 books = {{{highlight_green(800D/3)}}} cents (CHOICE 4)
