Dory and nemo go to Taco Bell for lunch. dory orders three soft tacos and three double deckers for $11.25 nemo pays $10.00 for four soft tacos and two double deckers. write a system of equations that represents the lunch orders for dory an

d memo use x to represented soft tacos an y to represent double deckers

If we let x be the price for soft tacos and y be that of double deckers, then from the question, we'll have 3x + 3y = 11.25 x + y = 11.25/3 x + y = 3.75 (1) in addtion, we also have 4x + 2y = 10.00 2x + y = 5.00 y = 5.00 - 2x (2) Substituting y from equation (2) into equation (1), x + (5.00 - 2x) = 3.75 - x = 3.75 - 5.00 x = 1.25 y = 5.00 - 2 (1.25) = 2.50
