**Reiny**, Thursday, November 15, 2007 at 4:50pmlet the amount she had be $x

then she spent (1/5) and (1/5)(4/5)x

the sum of that is 36.

Can you take it from there?

for your second part

remember that the only way that 100/(p^2-16) cannot have a value is when we divide by zero.

so when is p^2 - 16 = 0???
