Find the original price of a bag of fruits?

Question

One week Jordan bought a bag of fruits at the local market.The next week he saw the bag was on sale for 20℅ off the previously marked price.Jordan bought two more bags at the reduced price and spent $20.54 in total for the three bags

Answer 1

Take $x$ to be the original price. Jordan buys one bag at this price. The next week he buys 2 bags for $0.8x$ each after allowing 20% off.
The total amount paid by him for the 3 bags is $x+0.8x\times 2$=$2.6x$=20.54 (given).
Thus $x=7.9$.
