first you need to find out how much of each color dana needs to buy. she needs
43 red, 49 green, 66 yellow and 75 blue. the you take 43 times .25 to get 10.75,
then you take 49 times .25 to get 12.25 then you take 66 times .25 to get 16.50
and then you times that by .30 for the 30% off and you get 11.55 after that you
take 75 times .25 and get 18.75 and times that by .30 for the 30% and you get
13.125 which rounded up is 13.13. then you take 10.75 plus 12.25 plus 11.55 plus
13.13 and your answer is that she needs 47 dollars and 68 cents to buy all the
pickets she needs
