A manufacturer secures two parts of its finished product with an epoxy-type adhesive. Unlike normal glue, the adhesive comes in two parts, an epoxy resin and a separate hardner. As soon as the two are mixed, the combination goes through a chemical reaction that creates a permanent bond.
The company buys 3 big drums full of epoxy resin, and 5 big drums of the hardener. The epoxy resin costs $48 dollars more per drum than the hardner. In total, the company pays $720 for all 8 drums. Which of the following are true? Select all that apply.
