Answer 1

Answer:

All together she had a 18.1818182% raise but 18% raise rounded.

Step-by-step explanation:

First you need to find how much each stock increased.

So:

1700 to 2040

500 to 560

Add them.

1700 + 500 = 2200

2040 + 560 = 2600

Then find the raise. You can usally just find the amount for each percent or find the over all raise.

1% of 2200 is 22

400/22 = 18.18
