Callie had $24.65 to spend on groceries after buying six potatoes. She had $18.95 left each potato cost. The same amount was the price of one potato.

To find the total cost of the six potatoes, we first need to subtract the amount Callie had left after buying the six potatoes from the amount she had initially.

Initial amount Callie had = $24.65
Amount she had left after buying 6 potatoes = $18.95

Amount spent on 6 potatoes = Initial amount - Amount left
= $24.65 - $18.95
= $5.70

So, Callie spent $5.70 on 6 potatoes. To find the price of one potato, we divide this amount by the number of potatoes purchased.

Price of one potato = Total cost of potatoes / Number of potatoes
= $5.70 / 6
= $0.95

Therefore, each potato cost $0.95.
