• 0.5
• 20
• 500
• 2

Explanation:
They should set a $2 target cost per install (tCPI) when starting a new Google App campaign for installs. This figure is derived from dividing the historical revenue ($1,000) by the number of installs (500), resulting in a $2 tCPI. Starting with this value aligns the campaign with previous performance, ensuring a cost-effective approach to acquiring new users. Additionally, Google recommends setting a daily budget at least 50 times the tCPI, making $2 a suitable starting point to optimize performance and budget efficiency.
