To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan’s gift card had $1.90 remaining.

Which equations could you use to find the price of one tire patch? Select all that apply.
4x – 1.9 = 22.2
4x – 22.2 = 1.9
4x + 1.9 = 22.2
4x + 22.2 = –1.9
22.2 – 4x = 1.9

The equation that could be used to find the price of one tire patch is:

4x - 1.9 = 22.2

This equation represents the scenario where Rhyan bought four tire patches, paid $1.90 from his gift card, and the remaining balance on the gift card was $22.20. By solving this equation, we can determine the price of one tire patch (represented by x).
