Amaya went to a department store and bought 3 pairs of shoes. The cheapest pair of shoe cost P 350.25. The second pair was twice as much as the first pair. The third shoe is P 275.75 more than the first pair. She paid 2 P 1000-bill to the cashier. How much was her change?
320.25+640.5(it said twice so 320.25×2)+596(it said more than the first pair so 320.25+275.75)= 1556.75 and 1556.75-2000(it ask of how much was his change)
