Amazon Dynamo DB price quiz

I’m learning AWS Certified Developer Associate 2018 Practice Quiz.

Question 1 "In DynamoDB, if you create a table and request 10 units of write capacity and 200 units of read capacity of provisioned throughput, how much would you be charged in US East (Northern Virginia) Region? "

  1. $ 0.05 per hour
  2. $ 0.10 per hour
  3. $ 0.03 per hour
  4. $ 0.15 per hour

My calculation is this.

$0.00065 × 10 + $0.00013 × 200 = $0.0325 per hour

But the answer is this.

$ 0.01 + (4 x $ 0.01) = $ 0.05 per hour "

What is “4”???

Knowledge Area: http://aws.amazon.com/dynamodb/pricing/

I didn’t understand 😔 Please help me. Thank you.

The question seems premised on obsolete information.

Previously, DynamoDB capacity was sold in blocks of 10 WCU and 50 RCU, each of which was $0.0065. (It may have been $0.01 several years ago, since AWS does sometimes decrease pricing when new technologies or efficiency gains permit it or this might be the result of rounding.) The 4 is 200 ÷ 50.
