Bingel [31]

Answer:

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% = \frac{47}{100}

∴ The number of games for Xbox = \frac{47}{100} × 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% = \frac{53}{100}

∴ The number of games for PS4 = \frac{53}{100} × 330

∴ The number of games for PS4 = 174.9

∴ The number of games for PS4 ≅ 175
