Question

Tommy has three times as many video games as Griffin. Fletcher has eight less than Tommy. The total number of video games is less than 40. Circle the number that represents the greatest number of video games that Fletcher can own?

Answer 1

x = 6.86

Number of video games Fletcher has = 12.58

Explanation:

Let

Number of video games Griffin has = x

Number of video games Tommy has = 3x

Number of video games Fletcher has = 3x - 8

Total number of video games is > 40

Griffin + Tommy + Fletcher > 40

x + 3x + (3x - 8) > 40

4x + 3x - 8 > 40

7x > 40 + 8

7x > 48

x > 48 / 7

x > 6.86

Number of video games Fletcher has = 3x - 8

= 3(6.86) - 8

= 20.58 - 8

= 12.58
