<human>:  On an American flag, the first stripe is red and half of the remaining stripes are also red. Each flag has 13 stripes. John buys 10 flags. How many red stripes are there?
<bot>: How many stripes are left? ** There are 13-1=<<13-1=12>>12 stripes left
How many red stripes are there? ** So there are 12/2=<<12/2=6>>6 red stripes
How many red stripes are there? ** So the total number of red stripes is 6+1=<<6+1=7>>7 red stripes
How many red stripes does John have? ** So he has a total of 7*10=<<7*10=70>>70 red stripes
