1) Just move the decimal two places to the right to get the percent.
2) n/15 = 8/10 Solve for n
3) P = 10 + B
P + 7 = 2(B+7)
Solve for P(Paige) and B(Bro)

the point of doing homework is so that you can learn to think for yourself. That is easy stuff, learn it now because it's only going to get harder.

are you sure you're not just lazy and don't want to do this? Did you check in your book or your notes?
