Jada is trying to determine the number of t-shirts that were in inventory before she started her shift. During her shift, she sold thirteen t-shirts, which left twenty-two t-shirts in inventory.
-Define a variable.
-Write an equation Jada can use to determine the number of t-shirts that were in inventory before she started her shift.
- Solve the equation showing your work.
X = number of shirts
X - 13 = 22
Solve for X.
x = 35
1. Variable: Let's define the variable as "x" to represent the number of t-shirts in inventory before Jada's shift.
2. Equation: Using the information given, we can write the equation:
x - 13 = 22
The left side of the equation represents the initial inventory before Jada sold any t-shirts (x), and the right side represents the remaining inventory after she sold thirteen t-shirts (22).
3. Solve the equation:
To solve for x, we need to isolate it on one side of the equation. We can do this by adding 13 to both sides of the equation:
x - 13 + 13 = 22 + 13
This simplifies to:
x = 35
Therefore, there were 35 t-shirts in inventory before Jada started her shift.
