Let \( p \) be the price per hot wing.
The total amount spent by the first customer can be represented as: \[ 8p + 4 \] The total amount spent by the second customer is: \[ 10p + 2.80 \]
Since both customers spent the same amount, we can set up the equation: \[ 8p + 4 = 10p + 2.80 \]
Now, we can solve for \( p \):
-
Subtract \( 8p \) from both sides: \[ 4 = 2p + 2.80 \]
-
Subtract \( 2.80 \) from both sides: \[ 4 - 2.80 = 2p \] \[ 1.20 = 2p \]
-
Divide both sides by 2: \[ p = \frac{1.20}{2} = 0.60 \]
Thus, the price per hot wing is: \[ \boxed{0.60} \] (dollars).
