Answer:
2040
Step-by-step explanation:
We know Appleville is predicted to double its population every 10 years, while Brigdetown simply adds 1000. Doing the math, the 2040 Census will be the first one where Appleville's population (8,000) will be larger than Bridgetown's (7,000).
Appleville: 1,000 * 2³ = 1,000 * 8 = 8,000 people in 2040
Bridgetown: 4,000 + 3(1,000) = 4,000 + 3,000 = 7,000 people in 2040
8,000 > 7,000, so 2040 will be first census year where Appleville is larger than Bridgetown. (I know this is extra, but if this was asking for first year overall, then it would be 2037. 6,800 > 6,600)
