Anna, ben, and cindy have m markers together. anna has a markers, and this is twice as many markers as ben has. how many markers

SOVA2 [1]

So, Anna has a markers, Ben has b markers and Cindy has c markers.
We know that a+b+c = m.
And we know also that a = 2b. (<span> twice as many markers as ben has</span>)
(Remember b is the number of Ben markers.)
The equation becomes:
2b+b+c=m.
Solving for c:
$c=m-3b$
Cindy has (m-3b) markers.

Ratling [72]

Find the unit rate, or cost of 1 gallon.

576/24=$24 per gallon
1664/64=$26 per gallon.

Paul's Paint sells paint for the least amount as 24<26.
There is a $2 difference.
