3x + 2y = 36.5 \\ 2x + 5y = 50
3x + 2y = 36.5 \: \: \: (1)\\ 2x + 5y = 50 (2)\\ 2x = 50 - 5y \\ x = \frac{50 - 5y}{2} \: \: \: \: \: \: \: \: (3) \\ put \: 3 \: into \: 1 \\ 3 \frac{50 - 5y}{2} + 2y = 36.5 \\ \frac{150 - 15y}{2} + 2y = 36.5 \\ 2( \frac{150 - 15y}{2} + 2y) = 2(36.5) \\ 150 - 15y + 4y = 73 \\ 11y = 77 \\ y = 7 \\ 2x + 5(7) = 50 \\ x = 7.5 \\ wage \: working \: in \: coffee \: shop \: is \: higher \: for\: 7.5 \: per \: hour

IgorLugansk [536]
After 500 years one would have N nuclei of the original substance.

N = 100 * exp ( -ln(4) ) = 25

LOL.

I guess it is exp( - lamda * t)

Lamda, the decay constant is the ln(2) over the half life.

So we get exp( -ln(2)/250 * 500) or exp ( -ln(4) )
