Step-by-step explanation:
The correct answer is:
11.3
Explanation:
In 10 days, the population x would double, becoming 2x.
Every 10 days after, the population would double again. This means at 20 days, the population would be 2(2x) = 4x, and at 30 days, the population would be 2(4x) = 2(2(2x)) = 8x.
Writing the repeated multiplication out, we see that this can be represented with exponents. 10 days would be 2¹(x); 20 days would be 2²(x); 30 days would be 2³(x).
5 days would not be adding a whole number to the exponent, as it is only half of the time it takes to double. This means we would add 0.5 to the exponent; this would make 35 days
, which comes out to 11.3x. This means it increases by a factor of 11.3 in 35 days.
