Answer 1

c = ½(p + 2s)

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

c = ½(p + 2s)

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)
