Let's assume the total number of birthday cards in the stack as "x".
According to the given information, Meg and Grandma Pat have opened 46 cards, leaving 55 cards for later. So the equation becomes:
x - 46 = 55
Simplifying the equation, we can add 46 to both sides to isolate "x":
x = 55 + 46
Therefore, the total number of birthday cards in the stack is 101.
Meg's Great-Grandma Pat is turning 100 years old! The family throws her a party, and Meg helps her open a large stack of birthday cards. After opening 46 cards, they stop so Grandma Pat can blow out the birthday candles. Meg and Grandma Pat leave the remaining 55 cards for later.
Use an equation to find the total number of birthday cards in the stack.
