Check your last post. Please don't double post.
To find out the cost of the ice cream bar, we need to work backwards by adding up the missing amounts from both people and the remaining 1 cent.
Let's assume the cost of the ice cream bar is X cents.
Based on the information given, if he is missing 3 cents and she is missing 5 cents, we can set up the following equation:
X - 3 cents - 5 cents - 1 cent = 0
Simplifying the equation, we have:
X - 9 cents = 0
To solve for X, we can add 9 cents to both sides of the equation:
X = 9 cents
Therefore, the cost of the ice cream bar is 9 cents.
