dee went shopping she had 75 dollars to spend. At one store, she bought a dress and a tube of lipstick. The lipstick was half the price of the dress. she then spent half of what she had left on a pair of shoes. This left her with 13 dollars. How much was the dress and the lipstick?

75 - (d+d/2) - (75 - (d + d/2))/2 = 13

dress = 98/3 = $32.67
lipstick = 49/3 = $16.33
shoes = $13.00

check:
starting with 75,
dress+lipstick = 49
now she has 26
spent half of that = 13 on shoes,
leaving 13
remaining: 13
