The number of games for Xbox is about 155
The number of games for PS4 is about 175
Step-by-step explanation:
Let us find the numbers of games for Xbox and for PS4 game
∵ There are 330 video games in the store
∵ 47% of them were for Xbox
- Multiply 47% by 330
∴ The number of games for Xbox = 47% × 330
∵ 47% =
∴ The number of games for Xbox = × 330
∴ The number of games for Xbox = 155. 1
∴ The number of games for Xbox ≅ 155
∵ 53% of them were for PS4
- Multiply 53% by 330
∴ The number of games for PS4 = 53% × 330
∵ 53% =
∴ The number of games for PS4 = × 330
∴ The number of games for PS4 = 174.9
∴ The number of games for PS4 ≅ 175

Answer:
5 hours
Step-by-step explanation:
A quick way to look at this is to compare the difference in hourly charge to the difference in 0-hour charge.
The first day, the charge is $3 more than $12 per hour.
The second day, the charge is $12 less than $15 per hour.
The difference in 0-hour charges is 3 -(-12) = 15. The difference in per-hour charges is 15 -12 = 3. The ratio of these is ...
$15/($3/h) = 5 h
The charges are the same after 5 hours.
__
If you write equations for the charges, they will look like ...
y1 = 15 + 12(x -1)
y2 = 3 + 15(x -1)
Equating these charges, we have ...
15 +12(x -1) = 3 + 15(x -1)
12x +3 = 15x -12 . . . . . . . . eliminate parentheses
15 = 3x . . . . . . . . . . add 12-12x
x = 15/3 = 5 . . . . . . divide by 3
You might notice that the math here is very similar to that described in words, above.
The charges are the same after 5 hours.
