For a party, Mary has to bake 5 cakes, 3 pies, and 4 trays of cookies. One cake requires 2.5 cups of flour, one pie requires 1.25 cups of flour, and one tray of cookies needs 0.75 cups of flour. How much flour in all does Mary need to do the baking for the party?

5*2.5=12.5 cups needed for cakes
3*1.25=3.75 cups needed for pies
4*.75=3 cups needed for cookies
3+3.75+12.5= 19.25 cups needed in total
