Answer:
30 and 32
Step-by-step explanation:
30 31 32
We know that 7 cookies at the current price (75 cents less than normal) will cost $2.80.
Thus, we can set up the equation 7(c - .75) = 2.80
Now, let's solve for c.
c - .75 = .4
Add .75 to get:
c = 1.15

One can determine whether a binary tree is a binary search tree by traversing it in is In-order Traversal.
<h3>How do you traverse a binary search tree?</h3><h3>In-order Traversal</h3>
In this traversal method, the left subtree is visited first, then the root and later the right sub-tree. We should always remember that every node may represent a subtree itself. If a binary tree is traversed in-order, the output will produce sorted key values in an ascending order.
As,
In the case of binary search trees (BST), In-order traversal gives nodes in non-decreasing order.
For Inorder, you traverse from the left subtree to the root then to the right subtree.
To get nodes in non-increasing order, Inorder traversal s reversed can be used.
Hence, traversing is Inorder
