if a shirt is 45 % off and the sale price is 114.95-what is the original cost?
please help me with this formula
100% - 45% = 55% = 0.55
Let x = original cost.
0.55x = 114.95
x = ?
thank you ms. sue-i am the mom and could not figure the formula out!
You're welcome, Abbie :-)
Another way to do approach this problem is to divide 114.95 by 0.55 (which is what the equation does).

To find the original cost of the shirt, you can use the formula:
Original Cost = Sale Price / (1 - Discount Percentage)
In this case, the sale price is $114.95 and the discount percentage is 45%.
First, convert the discount percentage to a decimal by dividing it by 100:
45% / 100 = 0.45
Now, substitute the values into the formula:
Original Cost = $114.95 / (1 - 0.45)
Next, calculate the subtraction inside the parentheses:
Original Cost = $114.95 / 0.55
Finally, divide the sale price by the result to get the original cost:
Original Cost ≈ $114.95 / 0.55 ≈ $209.00
Therefore, the original cost of the shirt is approximately $209.00.
