Question 704500
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.
