A store is having its end year sale. A shirt now costs $7.98, which is half of its original price. Complete and solve the working equation that represents the original price, p, of the shirt.
Let's represent the original price of the shirt as "p". We know that the shirt is now being sold for half of its original price, so the equation that represents this information is:
p/2 = 7.98
To solve this equation for "p", we need to isolate the variable on one side of the equation. We can do this by multiplying both sides of the equation by 2:
2*(p/2) = 7.98*2
p = 15.96
Therefore, the original price of the shirt was $15.96.
