44

Step-by-step explanation:

Use this equation, were a represents the amount of strawberries sold:

4a+9(96-a)=644

Simplify the equation:

4a+864-9a=644

4a-9a=-220

-5a=-220

a=44

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.
