In the formula c=prn, p stand for a. percent b. price per item c. promotion d. period

p is price per item, the correct option is B

Step-by-step explanation:

Here we may have the comission equation, wich stands for how much a part (the store, the employe, etc) gets for every sale.

comission = price*number of sales*percent of comission

C = p*r*n

where p is the price, r is the rate of comission (a number smaller than one) and n is the number of items sold.

Then, we have that p = price per item.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
