First multiply the number of spots on the left side by 3: 16 spots * 3 = <<16*3=48>>48 spots
Then add 7 to find the number of spots on the right side: 48 spots + 7 spots = <<48+7=55>>55 spots
Then add the number of spots on each side to find the total number of spots: 55 spots + 16 spots = <<55+16=71>>71 spots
