Mrs delgado needs to 160 begonias for her flowerbed. the prices for one plant is $1.79 and the prices for one flat is $30. how much would she save if she buy them by the flat instead of buying them separately.

Me with this assignment ! i only partially understand, so explain. also it's a work sample. at the championship bike race, steve and paula were fighting for first place. steve was 175 feet ahead of paula and had only 300 feet left to go. he was very tired and was going only 9 feet per second. paula was desperate to catch up and was going 15 feet per second. who won the bike race and by how far did she/he win?
