Paint express charges $30.00 per gal. of paintplus $1.10 per per sq.ft. of wall space. Color creations charges $24.00 per gal. plus $1.20 per sq.ft. of wall space. Robert estimates he will need 4 gal. of paint for the rooms he'd like painted. How much space would make Paint express less expensive than color creations?
