<human>:  Samwell owns an appliances store. For this week, one-fourth of their sales are smart TVs, one-eighth are analog TVs, and the rest are OLED TVs. If they were able to sell a total of 40 TVs, how many OLED TVs were they able to sell?
<bot>: How many smart TVs did Samwell sell? ** Samwell was able to sell 1/4 x 40 = <<1/4*40=10>>10 Smart TVs.
How many analog TVs did Samwell sell? ** He was able to sell 1/8 x 40 = <<1/8*40=5>>5 analog TVs.
How many TVs did Samwell sell? ** So, he was able to sell 10 + 5 = <<10+5=15>>15 Analog and Smart TVs.
How many OLED TVs was Samwell able to sell? ** Therefore, the total number of OLED TVs that he was able to sell is 40 - 15 = <<40-15=25>>25.
