Answer 1

Answer:

c = ½(p + 2s)

Step-by-step explanation:

 Let c = the total cost

       p = cost of one shirt

     2s = cost of two sweaters

p + 2s = total cost before discount

But Alana paid only half the regular price, so

c = ½(p + 2s)

Answer 2

Answer:

c = ½(p + 2s)

Step-by-step explanation:

Let c = the total cost

      p = cost of one shirt

    2s = cost of two sweaters

p + 2s = total cost before discount

But Alana paid only half the regular price, so

c = ½(p + 2s)
