Nadia was sent to the flower shop to buy 20 roses and 3/4 times as many Lillies as roses. If roses cost $5 each and lilies cost twice as much each, calculate the total amount of money Nadia used to buy the flowers.

How much do roses cost? ** The total cost for roses is 20*5 = $<<20*5=100>>100
How many lilies did Nadia buy? ** Nadia bought 3/4*20 = <<3/4*20=15>>15 lilies.
How much do lilies cost? ** Each lily costs 5*2 = $<<5*2=10>>10
How much money did Nadia use to buy lilies? ** She used 10*15 = $<<10*15=150>>150 in total to buy lilies.
How much money did Nadia use to buy the flowers? ** To buy all the flowers, Nadia used 150+100 = $<<150+100=250>>250
