Define a variable ** Let H be the number of hoodies Fiona owns.
How many hoodies does Casey own? ** Casey owns H + 2 hoodies.
How many hoodies do Fiona and Casey own together? ** Together, they own H + H + 2 = 2H + 2 = 8 hoodies.
How many hoodies do Fiona and Casey own together? ** Thus, 2H = 8 - 2 = 6 hoodies.
How many hoodies does Fiona own? ** Therefore, Fiona owns H = 6 / 2 = <<6/2=3>>3 hoodies.
