Video Summary

Celia's favorite chocolate bars originally came in packets of five bars, now reduced to four bars, but sold at the same price. The task is to determine the price increase per bar. Assigning variables, the packet price is P. Initially, the cost per bar was P/5. Now, with only four bars, the cost per bar is P/4. Calculating the percentage increase involves finding the difference divided by the original price: \((P/4 - P/5) / (P/5) = 25\%\). Therefore, the price increase per bar is 25%, making the answer C.
