I’ll give the Brainliest to who answers this question with a reasonable explanation. If Jan can buy 12 copies of a certain book for $40, what is the unit rate for cost per copy? How much would it cost her to buy 18 copies at the same rate?

Thank you!

$40/12 = unit rate simplify = 10/3
$10/3 per book
18 * 10/3 = $60 for 18 copies

After the experience with great britain having a monarchy, the united states realized that everyone needed to have a voice in the government. the fact that americans had no voice was the main reason for the war. thus, they created a democracy, where the people voted for their representatives and the government ruled with the consent of the people.
