The science club went on a two-day field trip. the first day the members paid $30 for transportation plus $12 per ticket to the planetarium. the second day they paid $90 for transportation plus $9 per ticket to the geology museum. write an expression to represent the total cost in dollars for two days for the n members of the club.

 Total: 30 + 20y + 85 + 17y  This is the not simplified version.

37y+115 This is the simplified version. Hope this helps

Step-by-step explanation: I really don't know the steps.?

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
