To make a profit, the prices of the items sold in a furniture store are marked up by 80%. after marking up the prices, each item is put on sale at a discount of 10%. design an algorithm to find the selling price of an item sold at the furniture store. what information do you need to find the selling price?

7. design a circuit with three inputs (x, y, and z) representing the bits in a binary number, and three outputs (a, b, and c) also representing bits in a binary number. when the input is 1, 2, or 3, the binary output should be one lesser than the input. when the input is 4, 5, or 6, the binary output should be one greater than the input. when the input is 0, the output is 0, and when the input is 7, the output is 7. show your truth table, all computations for simplification, and the final circuit.
