Mr. Digman is selling his famous Peanut Butter and Jelly sandwiches for $1.50 a piece and ham sandwiches for $2.00 a piece. During his rush, he didn't keep track of how much of each sandwich he made but knows that he made 32 sandwiches based on how much bread is gone. He also knows that he made $55.50 from the sandwich sales. How many of each sandwich did he sell?

8121 because

130,000 divided by 16 is 8121

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.

5 feet of chain cost $9

so the answer is 1.80
