Answer 1

Answer:

Step-by-step explanation:

cost price + profit = selling price

cost price = sp - profit

cost price = 6890-390

cost price = 6500

Answer 2

Answer:

6500

Step-by-step explanation:

We have P (profit)= 390

SP (selling price)= 6890

CP ( cost price)= ?

We have to find CP.

Let the CP be x.

Formula of profit = Selling price-Cost price= SP-CP

P= SP-CP

390= 6890-x (To make x positive, take x to left side)

390+x= 6890

x= 6890-390

x= 6500

Cost price is 6500.
