over a period of ten years Pats income rose from 15000 to 20000 round to the nearest whole number by what percentage did her inc

ludmilkaskok [199]

Original Income = 15,000
New income = 20,000

The percentage Increase in the income can be calculated as:

$\frac{Change}{Original} * 100$ %

The change in income = 20000 - 15000 = 5000

Using the values, we get:
