COMPLETE SOLUTION: Create a system of linear equations. Then, solve the system using Cramer’s rule. A family of 3 people went out for dinner in a restaurant. The cost of two chicken, three rice and two drinks is P150. The cost of the two chickens, two rice and four drinks is P200. The cost of five chicken, four rice and two drinks is P250. The family has P350 in hand and they ate 3 chickens and six rice and six drinks. Will they be able to manage to pay the bill within the amount they had?
