Answer:
[tex]y = 75 + 10x[/tex]
Step-by-step explanation:
Given
New Video Games
[tex]Cost = \$25[/tex]
[tex]Number = 3[/tex]
Used Video Games
[tex]Cost = \$10[/tex]
[tex]Number = x[/tex]
Required
Determine the amount spent (y)
First, we need to determine the total spent on new games
1 new game = $25
3 new games will be: 3 * $25
Next, we determine the total spent on old games
1 used game = $10
x used games will be: x * $10
So, total amount y, is:
[tex]y = 3 * 25 + x * 10[/tex]
[tex]y = 75 + 10x[/tex]
