Rebekah used a total of 144 tiles to make 4 placemats. She used 32 tiles each to make two placemats and y tiles to make the third placemat. Which equation can be used to find t, the number of tiles used for the fourth placemat? A. (= 144 - 32(2 •y) 0 B.+ t = 144 - 2(32 + y) C. t = 144 - (y• 2) - 32 D. t = 144 - (32.2) - y​
