Answer:
the original price of the shirt was $70.
Explanation:
Let's use the variable "p" to represent the original price of the shirt. Then, we know that the sale price is 60% of the original price, which can be written as:
0.6p
We also know that the original price is $28 more than the sale price, so we can set up another equation:
p = 0.6p + 28
Now we can solve for p:
p = 0.6p + 28 (subtract 0.6p from both sides)
0.4p = 28 (simplify by combining like terms)
p = 70 (divide both sides by 0.4)
Therefore, the original price of the shirt was $70.
