Question

Mary has $50.00. She goes to the mall and buys lipstick and then she buys shampoo, which is

half the price of the lipstick. She then spends half of what she has left on a purse, leaving her
with $15.00. How much did the shampoo cost? How much did the lipstick cost?

Answer 1

Thank shampoo costed $7.50 and the lipstick costed $15

Explanation:

So if you subtract 15 by 50 you get 35 dollars. Then if you divide 35 by 2 you get 15.5 but the .5 is no important right now. So that's how you get 15 dollars for the lipstick and the shampoo was $7.50. The purse was $12.50.

Answer 2

Hey there!

Let x be the price of lipstick

Let 1/2x be the price of shampoo

1.5x=20

x=13.33

1/2x=6.67

The shampoo costed $6.67, and the lipstick costed $13.33
