Question

Kimmy has played video games 24 hours over the last 9 days. She played either 2 hours a day or 3 hours a day. During the 9 day period, how many days did Kimmy play for two hours a day?

Answer 1

Answer:

The number of days when Kimmy play for two hours a day is 3.

Step-by-step explanation:

Let the number of days when Kimmy play for two hours a day be x. So, the number of days when Kimmy play for three hours a day is 9-x.

It is given that Kimmy has played video games 24 hours over the last 9 days.

$2(x)+3(9-x)=24$

$2x+27-3x=24$

$-x+27=24$

Subtract 27 from both the sides.

$-x=24-27$

$-x=-3$

$x=3$

Therefore the number of days when Kimmy play for two hours a day is 3.
