How many necklaces did the second machine make? ** The second machine made 2.4 times as many necklaces as the first machine, so the second machine made 2.4 * 45 = <<2.4*45=108>>108 necklaces on Sunday.
How many necklaces were made in total on Sunday? ** In total, 45 + 108 = <<45+108=153>>153 necklaces were made on Sunday.
