Americans had better supplies than the British forces.

On June 17, 1775, early in the Revolutionary War (1775-83), the British defeated the Americans at the Battle of Bunker Hill in Massachusetts. Despite their loss, the inexperienced colonial forces inflicted significant casualties against the enemy, and the battle provided them with an important confidence boost during the Siege of Boston (April 1775-March 1776). Although commonly referred to as the Battle of Bunker Hill, most of the fighting occurred on nearby Breed’s Hill.

On June 16, 1775, on the heels of the Battles of Lexington and Concord that kicked off the Revolutionary War, American troops learned that the British were planning to send troops from Boston to occupy the hills surrounding the city. Some 1,000 colonial militiamen under Colonel William Prescott (1726-95) built earthen fortifications on top of Breed’s Hill, overlooking Boston and located on the Charlestown Peninsula. (The men originally had been ordered to construct their fortifications atop Bunker Hill but instead chose the smaller Breed’s Hill, closer to Boston.)

Battle of Bunker Hill: June 17, 1775

On June 17, some 2,200 British forces under the command of Major General William Howe (1729-1814) and Brigadier General Robert Pigot (1720-96) landed on the Charlestown Peninsula then marched to Breed’s Hill. As the British Army advanced in columns against the Americans, Prescott, in an effort to conserve the Americans’ limited supply of ammunition, reportedly told his men, “Don’t fire until you see the whites of their eyes!” When the Redcoats were within several dozen yards, the Americans let loose with a lethal barrage of musket fire, throwing the British into retreat.

After re-forming their lines, the British attacked again, with much the same result. Prescott’s men were now low on ammunition, though, and when the Redcoats went up the hill for a third time, they reached the redoubts and engaged the Americans in hand-to-hand combat. The outnumbered Americans were forced to retreat. However, by the end of the engagement, the casualties of the Battle of Bunker Hill were high: Patriot gunfire had cut down some 1,000 enemy troops, with more than 200 killed and more than 800 wounded. More than 100 Americans perished, while more than 300 others were wounded. Three weeks later—on July 2, 1775—George Washington arrived in Cambridge, Massachusetts to take command of the Continental Army

i think its either b or c

explanation:

part a. there were 250 teenagers surveyed (100% of tenagers = 250)therefore 1 % = 250/100 = 2.5 76% = 1% x 76 = 2.5 x 76 = 190 teenagers of the 250 surveyed liked burgerspart b: jane surveyed 25% (which is equal to 50 teenagers, i.e. a quarter of the teenagers surveyed is 50) to get 100% we simply get 4 quarters, i.e. multiply 50 by 4 = 200 teenagers were surveyed by jane. part c: it is impossible to give an example where a percentage is greater than 100%, since, by definition , percentage means "per 100".
