You can put this solution on YOUR website!
Hint:

Translate the given statements/info into these equations

x+y = 80
0.3x+0.8y = 80*0.65

Solve the first equation for y to get y = 80 -x

Then plug this into the second equation to get

0.3x+0.8y = 80*0.65

0.3x+0.8(80 - x) = 80*0.65

Solve that for x, then use the solution for x to find the solution for y.

I'll let you do this. If you want to check the answers with me or if you still need help, see my email below. Thanks.
