A city doubles its size every 29 years. If the population is currently 300,000, what will the population be in 58 years?

Answers

Answer 1
Answer:

Answer:

1,200,000 or 900,000

Step-by-step explanation:

what i did was subtract 29 from 58 until i couldn't so 58-29=29 then 29-29=0 that 2. then i did 300,000*2=600,000. now if we double again like it says every 29 years then its 600,000*2=1,200,000. or you do 300,000+300,000=600,000 then 600,000+300,000=900,000
