Calculate Weeks and Show Friday as Ending Date

[Dee Wills]

Hi,

May I ask for help in writing a formula that will calculate and End Date that always lands on Friday based on a value entered into the Week Duration column.

	A	B	C	D
1	Task	Week Duration	Start Date	End Date
2	x	1	Monday, Jan 7, 2019	Friday, Jan 11, 2019
3	y	3	Monday, Jan 14, 2019	Friday, Feb 1, 2019

Essentially, I am aiming to always have my tasks managed in weekly blocks beginning on Monday and concluding on Friday after the number of allotted weeks.
If relevant to the formula, I'd prefer dates as 1/1/19. I used full dates above for illustration.

EXTRA HELP

I would love to either have holiday weeks (i.e. TG/Xmas) highlighted or skipped. I have dates on separate tab ready to be used as variables.

Thank you in advance for your help.

=b2+c2*7-weekday(b2)-1

Sorry, this does not seem to work. It puts the end date many years in the future.
