Pam laid three times as many tiles on Saturday as she laid on Sunday. If Pam laid 80 tiles over the weekend altogether, how many tiles did she lay on Saturday?

Saturday's tiles were three times Sunday's, so the two days make 3 + 1 = 4 equal parts. Each part is 80 ÷ 4 = 20 tiles. Saturday was 3 parts, or 3 × 20 = 60 tiles, so the correct choice is 60 tiles.
