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 and nemo. use x to represent soft tacos and y to represent double deckers.

We have to write the system of equations that represents the lunch orders for Dory and Nemo. We have to use x to represent soft tacoes and y to represent Double Deckers. For Dory: 3 x + 3 y = 11.25 and for Nemo: 4 x + 2 y = 10. We cal also oslve this system: 3 x + 3 y = 11.25 ( divide both sides by 3 ); x + y = 3.75; x = 3.75 - y; then we have to put it into the other equation: 4*( 3.75 - y ) + 2 y = 10; 15 - 4 y + 2 y = 10; 2 y = 5; y = 2.50; x = 3.75 - 2.50 = 1.25. Soft tacoes cost $1.25 and Double Deckers cost $2.50. The system of equations is: 3 x + 3 y = 11.25 and 4 x + 2 y = 10.
