Solve the following using Cramer's rule. A family of 3 people went out for dinner in a restaurant. The cost of two dosai, three idlies and two vadais is Php150. The cost of the two dosai, two idlies and four vadais is Php200. The cost of five dosai, four idlies and two vadais is Php250. The family has Php350 in hand, and they ate 3 dosai and six idlies and six vadais. Will they be able to manage to pay the bill within the amount they had ? Let "x", "y" and "z" be the cost of 1 dosa, 1 idly and 1 vada respectively. 2x + 3y + 2z = 150 2x + 2y + 4z = 200 5x + 4y + 2z = 250
