Price is marked down by 60% with an additional discount of 15% on the marked down price
Suppose x is the original price of the item
After marking down, it is
![\Rightarrow x-x* 0.6=0.4x](https://img.qammunity.org/2022/formulas/mathematics/high-school/b7hb79ljsm8ha3h1z87cltlsvac45j89rw.png)
after additional discount it is
![\Rightarrow 0.4x(1-0.15)=0.4x* 0.85=0.34x](https://img.qammunity.org/2022/formulas/mathematics/high-school/7r9cp8mflemnon0zniy66lzis2yqqasvrd.png)
Effective discount on the item is
![\Rightarrow (x-0.34x)/(x)* 100=66\%](https://img.qammunity.org/2022/formulas/mathematics/high-school/94zu1nlyoat1sryuxvxhyx729688dwoo81.png)
Thus, a person is paying
