Given, Amy made a reservation for dinner at a restaurant three weeks after the second Friday after \(2^{nd }\) December, \(2021\).
Let’s find the date of the second Friday after \(2^{nd }\) December.
Let’s start moving forward starting from \(2^{nd }\) December, one date at a time.
We will stop when we reach the second Friday after \(2^{nd }\) December
So, the date of second Friday after \(2^{nd}\) December is \(10^{th}\) December.
Let’s find the date three weeks after \(10^{th}\) December.
There are \(7\) days in a week.
So, \(3\) weeks \(= 7 + 7 + 7 = 21\) days.
\(10 + 21 = 31\)
So, the date three weeks after \(10^{th}\) December is \(31^{st}\) December.
So, Amy made a reservation for dinner in a restaurant on \(31^{st}\) December.
