The charges for the usage of per m3 of water and per kWh of electricity are $1.94 and 26 cents respectively. In May, Mr Kumar used x m3 of water and y kWh of electricity and his bill came to $272.10. In June, his bill came to $202.60 for the usage of (x-5) m3 of water and (3y - 1950) kWh of electricity. Form two equations in x and y and solve these two equations to find the total cost of using (x+8) m3 of water and (2y-725) kWh of electricity.
