Hello!

to solve this, do the following equation:
x=brand x copier
y=old version

x=y+(y*.1)  or  x=y*1.1

using either of these equations, the math I will show will get you the correct answer

462=420+(420*.1)  or  462=420*1.1

your final answer is:  the new copier produces 462 copies per hour

I hope this helps, and have a nice day!

462
