A movie theatre sells tickets for $8.50 each. The manager is considering raising the prices but knows for every 50 cents the price is raised, 20 fewer people go to the movies. The equation R=-40c^2+84c describes the relationship between the cost of tickets, c dollars and the amount of revenue, R dollars, that the theatre makes. What price should the theatre charge to maximize revenue?
This question has me really stumped and I don't know quite where to begin any help would be greatly appreciated.

Both NaCl and CaO crystallize in the same lattice structure. Account for the following: The melting point of CaO is 2899°C while that of NaCl is 800°C. Mark all of the following that contribute to this difference in melting points.


Calcium ion has a larger charge than sodium ion.
The ionic radius of chloride ion is larger than an oxide ion.
NaCl has a higher molar mass than does CaO.
Oxide ion has a larger charge than chloride ion.
Calcium ions and sodium ions have similar ionic radii.

1. stratum corneum, nails, hair, stratum basale

2. radiation, absorption, conduction, evaporation

i know radiation and evaporation are similar since both are 2 ways skin help get rid of body heat so it's either absorption or conduction, i think.

thanks for the help.
