william sold 5 oven toasters and 3 rice cookers for 500$. if a rice cooker cost 20$ less than an oven toaster, find the cost of a rice cooker

Total price=$500 Let cost of cooker be x Cost of oven = x-20 So cost of rice cooker = 5 (x-20) + 3x=500 5x-100+3x=500 8x-100=500 8x=500-100 8x=400 x=400/8 x=50 So price of cooker=$50
