I dont understand your question
Answer: The work of Isaac Newton identified certain laws of physics "laws of motion" that helped define the movement of the planet around the sun, thus further confirm the idea that sun was center of solar system, an idea which had been earlier proposed by Nicolaus Copernicus, an astronomer from Poland.
Explanation:
Hey there!
To solve this problem, all you need to do is calculate what 15% + 10%, or 25%, of $400.00 is. You can convert percentages into decimals by moving the decimal point as such: 15% becomes 0.15, and vice versa.
To solve for how much 25% of 400 is, you need to multiply:
$400.00 * 0.25 = $100.00
So, since she's giving $100.00 of the money to the local library and her manager, she takes home the rest.
$400.00 – $100.00 = $300.00
Hope this helped you out! :-)
