Question

It takes Dimitri 9 minutes to make a simple bracelet and 20 minutes to make a deluxe bracelet. He has been making bracelets for longer than 120 minutes. If x represents the number of simple bracelets that he has made and y represents the number of deluxe bracelets he has made, the inequality 9x + 20y > 120 represents the scenario. Which is a possible combination of bracelets that Dimitri may have made? 3 simple bracelets and 4 deluxe bracelets 0 simple bracelets and 6 deluxe bracelets 12 simple bracelets and 0 deluxe bracelets 7 simple bracelets and 3 deluxe bracelets

Answer 1

Last one 7 and 3
9(7)+20(3)>120
63+ 60
123>120
Says 123 minutes is longer than 120 that's why it is that answer

Answer 2

1st case ,  27 + 80 = 107 > 120  incorrect

2nd case, 0+ 120 = 120 > 120  , incorrect

3rd case, 108 + 0 =108 > 120 , incorrect

4th case, 84 + 60 = 144 > 120 , correct

so, option d) 7 simple bracelets and 3 deluxe bracelets
