Question

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.

Answer 1

Dory: $11.25= x+x+x+y+y+y or $11.25= (3*x)+(3*y)

Nemo: $10.00=x+x+x+x+y+y or $10.00= (4*x)+(2*y)
This is your answer

Answer 2

Answer: Required system of equations that represents the lunch orders for Dory and Nemo is given by

`3x+3y=\$11.25---------------(1)\\\\4x+2y=\$10.00------------------(2)`

Explanation:

Let the cost of soft tacos be 'x'.

Let the cost of Double deckers be 'y'.

According to question, Dory orders three soft tacos and three double deckers for $11.25.

`3x+3y=\$11.25---------------(1)`

Similarly, Nemo pays $10.00 for four soft tacos and two Double Deckers.

`4x+2y=\$10.00------------------(2)`

So, cost of soft tacos is $1.25 and Cost of double decker is $2.5.

Hence, Required system of equations that represents the lunch orders for Dory and Nemo is given by

`3x+3y=\$11.25---------------(1)\\\\4x+2y=\$10.00------------------(2)`
