<human>:  A craftsman makes 16 jars. This is exactly twice the number of clay pots he made. If each jar has 5 marbles and each clay pot has three times as many, how many marbles are there?
<bot>: How many clay pots are there? ** 16 jars are exactly twice the number of clay pots made by the craftsman, meaning there are 16/2=<<16/2=8>>8 clay pots
How many marbles are there? ** If each jar has 5 marbles, the total number of marbles in the jars is 5*16=<<5*16=80>>80
How many marbles are in each clay pot? ** Each of the clay pots also has 3*5=<<3*5=15>>15 marbles.
How many marbles are in the 8 clay pots? ** The total number of marbles in the 8 clay pots is 15*8=<<15*8=120>>120
How many marbles are there? ** There are a total of 120+80=<<120+80=200>>200 marbles.
