Laurel needs to purchase at least 40 party decorations. The Party Palace charges $0.50 per decorative streamer and $0.25 per balloon, including tax. Which combination of streamers and balloons can Laurel purchase with $16.00 at the Party Palace?

she can  buy 20 balloons and 10 streamers

Explanation:

First you multiply 16 by 100 then divide by 25 and you will get 64

then you multiply 16 by  100 again but this time divide by 50 and you will get 32

you then multiply them together and divide by 2

and you will get 1024

so if you divide that by 2

you will get 5.12 meaning she spent 5.12 for streamers and 5.12 on balloons
