Alana buys one shirt with a regular price of p dollars and 2 sweaters with a regular price of s dollars. shes uses a coupon so that she pays only half the regular price. write an expression that shows how much money alana spends in all. then exlpain the expression.

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)

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
