Brenda already has $200 toward the purchase of a new laptop that sells for $450. she will save $50 each month, starting next month, until she can buy the laptop. which of the following represents the amounts she will have each month, starting next month, until she can afford to buy the laptop (assuming there is no sales tax)?
a. $200, $250, $300, $350, $400, $450
b. $250, $300, $350, $400, $450
c. $0, $200, $250, $300, $350, $400, $450
d. $50, $200, $450

B

Step-by-step explanation:

Amount Brenda has=$200

Total Amount Brenda needs for the laptop=$450

The amount remaining to purchase the laptop= $450-$200=$250

Amount saved each month=$50

Number of months needed to save $250= $250/$50= 5 months

Amount in 1st month of saving=$50+$200=$250

Amount in 2nd month of saving= $50+$250=$300

Amount in 3rd month of saving=$50+$300=$350

Amount in 4th month of saving =$50+ $350= $400

Amount in 5th month of saving= $50+$400=$450

Amount accumulated on the 5th month of saving = $450

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
