She would've bought 7 bags of apples, I believe.
Substitute y = -2x + 4 into 7y = -14x +28
7y = -14x +28
7(-2x + 4)= -14x +28
-14x + 28 = -14x +28
0 = 0

Answer:
$2.24
Step-by-step explanation:
Since we are trying to find a percentage of something, we can multiply whatever we're trying to find a percentage from by 0.X where X is equal to the number of the percentage. So in this case it's 15%. We can multiply $14.90 by 0.15 and we get 2.23500. Since we cannot have 2.235 dollars, we must round up decimal places.
The tip would be 2 dollars and 24 cents. ($2.24).
