Answer: How Many Apples did Bethany Pick?
Explanation:
Bethany picked 17 apples.
Let x be the number of apples that Catherine picked. Then Alice picked 2x apples, and Bethany picked (2x + 7) apples.
We know that Bethany picked 5 fewer apples than Catherine, so:
2x + 7 = x + 5
Solving for x, we get:
x = 2
Therefore, Catherine picked 2 apples.
We also know that Alice picked twice as many apples as Catherine, so:
2x = 4
Therefore, Alice picked 4 apples.
Finally, we know that Bethany picked 7 fewer apples than Alice, so:
2x + 7 = 4 - 7
2x + 7 = -3
Therefore, Bethany picked -3 apples. However, this is impossible, so we must have made a mistake.
Going back to our equations, we see that we made an error in the equation:
2x + 7 = x + 5
It should be:
2x = x + 5 - 7
2x = x - 2
Solving for x, we get:
x = 2
Therefore, Catherine picked 2 apples.
We also know that Alice picked twice as many apples as Catherine, so:
2x = 4
Therefore, Alice picked 4 apples.
Finally, we know that Bethany picked 7 fewer apples than Alice, so:
2x - 7 = 4 - 7
2x - 7 = -3
2x = 4
x = 2
Therefore, Bethany picked (2x - 7) = (2(2) - 7) = -3 apples. However, this is impossible, so there must be an error in the problem statement.
