Acandy bar is advertised as costing “three for $1.00” if jackie bought 21 andy bars at this price, how much money would she have saved if the price had been reduced to “seven for $2.00”?

Iwill give brainliest. give accurate answer, . suppose tommy walks from his home at (0, 0) to the mall at (0, 5), and then walks to a movie theater at (6, 5). after leaving the theater tommy walks to the store at (6, 0) before returning home. if each grid square represents one block, how many blocks does he walk?
