 Question 443443: 1. Sam and Max went to the Taco Barn for lunch. Max paid \$2.66 for three tacos and a medium drink. Sam paid \$3.70 for five tacos and a medium drink. a. Use the information provided to write a system of two equations. b. Use the substitution method to solve the system of equations. c. How much would the bill be for one taco and one medium drink? I need to show all work is this right? 3x + y = 2.66 (1) x = tacos, y = drink 5x + y = 3.70 (2) 2x = 1.04 x = 0.52 Sub in 1 3x + y = 2.66 1.56 + y = 2.66 y = 2.66 - 1.56 y = 1.10 Check in (2) 5x + y = 3.70 2.60 + 1.10 = 3.70 x = \$0.52 y = \$1.10 c. 1.10 + 0.52 = \$1.62 Click here to see answer by scott8148(6628)
