69 Beers (baby mode)

A Bar is using VRGDAs to price their beers. Jessy wants to buy a round (69 beers), but only has 1 ether to spend. Can you game the bar to buy the round?

Rules:

  1. Only modify testBuy69Beers() in Bar.t.sol in the designated section.

  2. Do not use cheatcodes

  3. Assume the VRGDA dependency is correct

  4. Get the test to pass!

Hint:

Spoiler! Chads begone!

VRGDAs set the price of a resource based on time and resources "purchased so far". As more resources are purchased, the price of each resource increases.
