Answer :
Final answer:
The subject of this question is Mathematics, specifically linear functions. the total cost in dollars of playing x games at arcade Z is given by the equation 25x.
Explanation:
The subject of this question is Mathematics, specifically linear functions. The question asks about the total cost of playing games at arcade W, which is represented by a linear function.
The total cost in dollars of playing x games at arcade W is given by the linear function y=0•25x+9. This means that the cost of each game is $0.25, and the cost of playing x games is given by y=0•25x+9.
To calculate the cost of playing a game at arcade Z, we can use the formula for the cost of playing x games at arcade W:
Cost of playing a game at arcade Z = Cost of playing 1 game at arcade W
We can substitute the formula for the cost of playing a game at arcade W into this formula to get:
Cost of playing a game at arcade Z = 0•25x + 9
To calculate the total cost of playing x games at arcade Z, we can multiply the cost of each game by the number of games played:
Total cost of playing x games at arcade Z = Cost of playing 1 game at arcade Z
We can substitute the formula for the cost of playing a game at arcade Z into this formula to get:
Total cost of playing x games at arcade Z = 0•25x + 9
We can simplify this equation by combining like terms:
Total cost of playing x games at arcade Z = 25x
Therefore, the total cost in dollars of playing x games at arcade Z is given by the equation 25x.
