Given that x^10 • x^m = x^100 and (y^3)^n = y^12, what is the
sum of m and n?

-1.9

Step-by-step explanation:

He has $1.10 in his printing account. 0.25 each sheet of paper.

47 pages.

He printed both sides so 47:2= 23.5.

Because he printed 2 pages then we divide by 2.

23.5:2=11.75

We cannot print a half of page, so we print 12 pages.

12*0.25=3

1.10-3=-1,9

His printing account will be in minus.
