Answer:
x = 15
Step-by-step explanation:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 +13 + 14 + 15 = 120
The number x is a positive integer.
You will need to use the compound growth formula - this is...
final number = starting number * (multiplier ^ number of years)
We can turn the 6% into a multiplier by dividing it by 100 and adding 1 on to it:
6/100 = 0.06
0.06+1 = 1.06
Then we can say that the starting number is 254 and the number of years is X, we can then place this all into the original formula:
Final population = 254 * (1.06 ^ X)
Hope this helps! :)
