get to hear. We're comparing banana prices. So we have 89 cents for one week, 79 cents for another week and 66 cents for another week. And we're not going about the decimal. We're just gonna keep the answer incense. So I look at the thing and I'm saying, Okay, we got something that 80 70 60 that's, like almost 90 80 and 60. Almost 70. I'm thinking it's gonna be somewhere. Um, if I had 90 and then 80 and ah, 70 buys average all them 80 would be my average, So I'm thinking it's gonna be somewhere near 80. Limit lower, though, because these air Although I went really high and all my numbers higher than what it was here. So I think it to be a little bit less than 80. So I'm gonna adam up together. Nine plus nyse 18 plus sticks would give me the 24 50 10 13. That's giving 23. So did 234 divided by three. That the seven Abby 21 to left over and three goes into 24 8 times. So yet 78 cents is the average, which is about what I thought I knew the 80 but lower than 80. So 78 cents
