Idon’t know which one to choose which one do u choose

A h+p ≤15

50h+500p ≥ 2500

Step-by-step explanation:

h = headphone and

p = pianos

We can only ship a maximum of 15 total

h+p ≤15

We must sell  at least 2500 dollars of product.  Headphones are 50 and pianos are 500

50h+500p ≥ 2500

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
