1)Each packet must have at least 20 gold stars = x > or equal to 20

Question

2)Each packet must have at least 15 silver stars = y > or equal to 15, is this correct?
3)The total number of stars in each packet must not be more than 60 = x+y < or equal to 60, is this correct?
4)x < 2y, two y is less than equal to x, is this right?

Answer 1

1) yes
2) yes
3) yes
4) If x<2y, then that would mean that 2y>x. So 2y is greater than x. There is no "or equal" sign in the original equation.
