On the last Friday of the month, workers can finish their work early and can go shopping, have a meal with their friends and go on a trip. The purpose of the policy is to promote their consumption. It started from Feb 24, 2017. The purposes are not only to promote consumption, but also to build their quality life styles they can feel fulfillment. この表現は自然ですか?
A: I think it’s all perfect except for ‘build their quality life styles they can feel fulfilment.’
A more natural way of saying this is ‘to improve their quality of life and lead them to a sense of fulfilment by having a work/life balance.’
Q: Premium fee will be charged based on JPY1,200. This USD $9.6 is an estimation.
A: The premium fee will be (charged) based on ¥1,200 JPY. The ($9.60) USD displayed here is an estimation.

We always use two decimal places when writing USD, even if the second decimal place is a zero because we say "nine sixty USD" (9.60), not "nine point six USD" (9.6).
When using JPY, USD etc. we put them after the numbers.
