A can of paint and a paint brush cost a total of $35. If the can of paint costs $30 more than the paint brush, how much does the paint brush cost?

35  30 = ?

math  Steve, Thursday, August 2, 2012 at 5:13pm
let the brush cost b dollars
then the paint costs b+30 dollars
together, they cost 35 dollars:
b + b+30 = 35
2b = 5
b = 2.50
brush: $2.50
paint: $32.50

Thanks, Steve. You're right.
I was wrong.
