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.

Oranges cost $1 each, so y=1

Jeremy buys six apples. So 6x
Total amount spent is $9


Subtract 2 from both sides

Divide both sides by 18
x=0.39
The cost of each apple is $0.39
The cost of each orange is $1
