Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes ne sells in a day. His daily earnings goal is $112.
Write an equation to determine how many pairs of shoes, D, Roger must sell in a day to meet his daily earnings
goal

Equation : y = 4.50D + 40

Number of pairs = 16

Step-by-step explanation:

It is given that:

Per day wage of Roger = $40

Commission on per pair of shoes = $4.50

Daily goal = $112

Number of pairs of shoes = D

Total earning = y

y = 4.50D + 40

112 = 4.50D + 40

4.50D = 112 - 40

4.50D = 72

Dividing both sides by 4.50

Therefore,

Equation : y = 4.50D + 40

Number of pairs = 16

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
