20s+5h=300

Step-by-step explanation:

Since $300 is the total amount of money needed, $300 can be the sum of the money gained from selling seats and hotdogs. From there, since it is $20 per seat and s is the number of seats sold, the expression to model the total amount of money from seats sold would be $20*s, or just 20s. The hotdogs are the same, since it is $5 per hotdog and h is the number of hotdogs sold, the expression to model the total amount of money from hotdogs sold would be $5*h, or just 5h.

You can add both of these expressions to find the total amount of money needed, which is $300, so 20s+5h=300.
