• The British soldiers were rowed across the bay to begin their march to Lexington and Concord. There were already 32 soldiers waiting on the shore, each boat could carry 16 soldiers. Write an equation to show y, the total number of soldiers on the shore after x boats crossed the bay.

• A private in the militia who turned out for the Lexington alarm received two pounds per month in pay. He also had five pounds in savings at home with his family. Write an equation to show y, the total amount of money the soldier had after x number of months.

• The British army had walked 5 miles on their way from Lexington to Concord. If the army continues to walk at a rate of 3.5 miles per hour, write an equation to show the relationship between y, the total number of miles traveled, and x, the number of hours it took.

• An American patriot in the war carried a bag of cannon balls weighing 3 pounds each plus a musket weighing 10 pounds. Write an equation that shows the relationship between y, the total number of pounds the patriot carried, and x, the number of cannon balls.
