Let's represent the number of apps on Sarah's phone as x.
Therefore, the number of apps on Rachel's phone is 4 + (4 * x).
The total number of apps on both girls' phones is x + (4 + 4x) = 115.
Combining like terms, we get 5x + 4 = 115.
Subtracting 4 from both sides, we get 5x = 111.
Dividing both sides by 5, we get x = 22.
Therefore, the number of apps on Sarah's phone is 22.
sarah and rachel each have apps on their phones. the number of apps on sarahs phone can be represented by x. the number of apps on rachels phone is 4 more times the number of apps on sarahs phone. the total number of apps on both girl's phones is 115. what is x the number of apps on sarahs phone?
