To solve this problem you have to convert the percentage to a decimal which would
be .40.
40% =40/100=.40
After doing so all you need to do is divide the amount needed by the percentage which gives you the amount she has saved.
225/.40= $90
Lauren has $90 saved
After rotation the output for point C´ would be ( - 2 . -3 ). There is also a graph showing rotation in the attachment.
