Answer:
Let the variable "x" represent the price of apples, and the variable "y" represent the price of oranges.
Lisa bought a dozen apples and two oranges.
Hence, she spent $[tex]$(12x+2y)[/tex]
Jeremy bought six apples, which means he spent $[tex]$(6x)[/tex]
The total is $11.
If we add up the variables from Lisa and Jeremy, we now know that
$([tex]18x+2y[/tex])=$11.
Since oranges cost $1 each, we can replace the variable y with $1.
$([tex]18x+2(1)[/tex])=$11
$[tex]$(18x+2)[/tex]=$11
Subtract $2 on both sides:
$[tex]18x[/tex]=$[tex]9[/tex]
Divide both sides by 18:
[tex]x=[/tex]$ [tex]0.50[/tex]
Apples are $0.50, whereas oranges are $1.
