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?
There are 13-1=<<13-1=12>>12 stripes left
So there are 12/2=<<12/2=6>>6 red stripes
So the total number of red stripes is 6+1=<<6+1=7>>7 red stripes
So he has a total of 7*10=<<7*10=70>>70 red stripes
