problem 3: stamps in an album
maria had some stamps in her album. she acquired 40 more stamps. she now has a total of 112 stamps. create an equation to represent the total number of stamps maria has. let ( \boldsymbol{downarrow} ) represent the number of stamps maria had before she acquired 40 more.
enter your equation in the first response box.
enter the number of stamps represented by ( \boldsymbol{downarrow} ) in this situation. enter your answer in the second response box.

Explanation:

Part 1: Equation

Step1: Define the variable

Let \( \downarrow \) be the number of stamps Maria had before.

Step2: Set up the equation

After acquiring 40 more stamps, the total number of stamps is 112. So the equation is \( \downarrow + 40 = 112 \).

Step1: Subtract 40 from both sides

To find \( \downarrow \), we subtract 40 from both sides of the equation \( \downarrow + 40 = 112 \).
\( \downarrow + 40 - 40 = 112 - 40 \)

Step2: Calculate the result

Simplifying both sides, we get \( \downarrow = 72 \).

Answer:

\( \downarrow + 40 = 112 \)

Part 2: Solve for \( \downarrow \)
