Tim is laying ceramic tile on a kitchen floor. each tile costs $3.19. how much do 100 tiles cost?

100 tiles cost $319. To get this answer, multiply the cost of one tile to the number of tiles, so 3.19x100 to give you $319.00. Hope this helps!!

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
