Let the cost of a hot dog be $h$ dollars and the cost of a bag of potato chips be $c$ dollars. From the given information, we can set up the following system of equations:1. $2h + 3c = 5.25$2. $4h + 4c = 9.00$Dividing the second equation by 4 gives $h + c = 2.25$. Solving this system of equations, we find that $h = 1.50$ and $c = 0.75$, which corresponds to choice A.
