As all we're given are variables, we'll pick easy numbers to calculate with.
This is an Alternative approach.

Say the car was produced for 100 dollars. Then it was sold for 120 dollars.
Then the dealer sold it for an additional 15%, giving a total of 120 + 10% + 5% = 120 + 12 + 6 = 138 dollars.
As d = 100, our answer is 138/100*d = 1.38d

(E) is our answer

Percentage increase 20% -> Multiplicity is 1.2
Percentage increase 15% -> Multiplicity is 1.15

For series of percentages multiply the above values: 1.2 * 1.15 = 1.38

Answer: E

Solution

Given:  
 • A car manufacturer produced a car at a cost of d dollars and sold it to a dealer at a price 20 percent higher than the production cost
• The dealer sold the car to a consumer for 15 percent more than the dealer paid for it

To find:  
 • The cost of the car to the consumer, in dollars

Approach and Working:  
 • The price at which the car was sold to the dealer = d + 20% of d = 1.2d dollars
• The price at which the car was sold to the consumer = 1.2d + 15% of 1.2d = 1.2d + 0.18d = 1.38d dollars

Hence, the correct answer is option E.

Answer: E

The manufacturer produced the car for 1 d dollars.
The manufacturer sold it to the dealer for 1.2 d dollars.  
The dealer sold it to the customer for (1.2 + 0.18) d dollars.  
The customer purchased it for 1.38 d dollars.
 
 Answer E

KSBGC · Answer

Production price = d
Selling price to dealer = 120% of d = 1.2 d

Selling price to customer = 1.2 d * 115% = 1.38 d

Thus the best answer is E.
