4. In January of 2021, there were 980,000 games available on the Apple App Store. By July of 2021, there were
984,200 games available. If we assume that the number of available games is steadily increasing at a
constant monthly (linear) rate,
a. What is the constant rate described in this scenario (slope)?
b. What is explicit formula for this scenario assuming the number of games in January 2021 is $P_0$?
c. How many games does this pattern suggest there were in January 2022?
d. At this rate, when (month and year) were there 1,000,000 games available for purchase in the Apple
