Answer:
8x+10y = 830
Explanation:
The variable x represents the number of cars that paid to park. The variable y represents the number of trucks that paid to park.
Since parking a car costs $8 per day, the expression to represent the cost of parking all x cars that parked that day is 8x.
Since parking a truck costs $10 per day, the expression to represent the cost of parking all y trucks that parked that day is 10y.
The expression for the total cost is 8x+10y.
We know the total was $830; this gives us the equation
8x+10y = 830.
