A dealer paid kshs 240,000 to an agent as commission for sale of a car .The commission was 3 percent of the car price how much m
dybincka [34]

Answer:

kshs 6,480,000

Step-by-step explanation:

Since, kshs 240,000 represent the 3% of the car price, you can use a rule of three to calculate the amount that represents 100%:

240,000 →   3%

     x       →  100%

x=(240,000*100)/3

x=8,000,000

So, the price of the car is kshs 8,000,000 and you can calculate the 16% of this, to find the amount that the dealer had to pay as government V.A.T:

8,000,000*16%=1.280.000

Now, you can subtract the comission and the government VAT from the car price:

8,000,000-240,000-1,280,000=6,480,000

According to this, the answer is that the dealer remained with kshs 6,480,000 from the sale of the car.
