A store is having its year in sale. A shirt cost $7.98 which is half of its original price complete and solve the working equation that represents the original price P of the shirt.
To solve the problem, we can set up the equation:
$7.98 = 0.5P
We want to find the original price P, so we need to isolate the variable on one side of the equation. Since $7.98 is equal to 0.5 times P, we can divide both sides of the equation by 0.5 to solve for P:
$7.98 / 0.5 = P
$15.96 = P
Therefore, the original price of the shirt was $15.96.
