Answer: The original cost was $27,400.
Explanation:
Since we have given that
Amount he paid for a delivery van = $35,620
Rate of markup = 30%
We need to find the cost.
Let the cost of delivery van would be 'x'.
So, Amount of markup would be
![(30)/(100)* x\\\\=0.3x](https://img.qammunity.org/2019/formulas/mathematics/high-school/oj389ngn2tj65fkn9hepoly3ux66doabh5.png)
Amount after mark up would be
![x+0.3x\\\\=1.3x](https://img.qammunity.org/2019/formulas/mathematics/high-school/2n83t27bt9jipnto5nipmrc0theqssls85.png)
According to question, it becomes,
![1.3x=35620\\\\x=(35620)/(1.3)\\\\x=27,400](https://img.qammunity.org/2019/formulas/mathematics/high-school/ry0f9ku4fidh9lax37shehpvy9mkfn0p0e.png)
Hence, the original cost was $27,400.
