Answer:
she ends at level 5 after her 3 turns
Explanation:
Rebecca starts at level 4 if she cuts down 6 trees for her next turn she loses 6 levels we can rewrite this as -6 so 4 + (-6) = -2 her next turn is planting 8 trees so she goes up 8 levels -2 + 8 = 6 her last turn she cuts down one tree
6 + (-1) = 5
altogether 4 + (-6) + 8 + (-1) = 5
