Final answer:
To find the percentage increase from 137k to 577k, calculate the difference between the two values, divide it by the original value, and multiply by 100.
Step-by-step explanation:
To find the percentage increase from 137k to 577k, we need to calculate the difference between the two values and then divide it by the original value and multiply by 100.
Step 1: Calculate the difference: 577k - 137k = 440k
Step 2: Divide the difference by the original value and multiply by 100: (440k / 137k) * 100 = 320.44%
So, the percentage increase from 137k to 577k is approximately 320.44%.
