Substitute x = 0 and y = 6 in the equation

LHS = 9*0 + 20*6 = 0 + 120 = 120

It should be grater than 120.The inequality is not satisfied. So, this is not the correct combination.

__Option 3__** :** 12 simple bracelets and 0 deluxe bracelets

Substitute x = 12 and y = 0 in the equation

LHS = 9*12 + 20*0 = 108 + 0 = 108 < 120

It should be grater than 120.The inequality is not satisfied. So, this is not the correct combination.

__Option 4__** :** 7 simple bracelets and 3 deluxe bracelets
