Answer:

The cost of each apple is $0.39

The cost of each orange is $1

Step-by-step explanation:

Lisa buys a dozen apples and two oranges.

Let 'x' be the cost of each apple

and 'y' be the cost of each orange

Lisa buys a dozen apples and two oranges.

[tex]12x+2y[/tex]

Oranges cost $1 each, so y=1

[tex]12x+2[/tex]

Jeremy buys six apples. So 6x

Total amount spent is $9

[tex]12x+2+6x=9[/tex]

[tex]18x+2=9[/tex]

Subtract 2 from both sides

[tex]18x=7[/tex]

Divide both sides by 18

x=0.39

The cost of each apple is $0.39

The cost of each orange is $1
