Karen and Alicia sell TVs. Last month Alicia sold 15 less TVs than Karen. Together they sold 99. How many TVs did Karen sell?

K + ( K- 15 ) = 99

2 K = 99 + 15 = 114

K = 57

x + x - 15 = 99

2x = 114

x = 57

Karen sold 57

To find out how many TVs Karen sold, we can set up an equation and solve it. Let's represent the number of TVs Karen sold as 'x'.

According to the information given, Alicia sold 15 less TVs than Karen. So the number of TVs Alicia sold can be represented as 'x - 15'.

Together, Karen and Alicia sold 99 TVs. So we can write the equation:

x + (x - 15) = 99

Now let's solve for x:

Combining like terms, we get:

2x - 15 = 99

Adding 15 to both sides:

2x = 114

Dividing both sides by 2:

x = 57

Therefore, Karen sold 57 TVs.
