<human>:  Ephraim has two machines that make necklaces for his store. On Sunday the first machine made 45 necklaces. The second machine made 2.4 times as many necklaces as the first machine. How many necklaces were made in total on Sunday?
<bot>: 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.
