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.

Answer 1

The answer is D: 7 simple bracelets and 3 deluxe bracelets

Answer 2

From my research the question had contained the following choices:

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

Given the inequality 9x + 20y > 120, it is easier to just substituting the answers from the choices and see which ones satisfy the inequality. From the choices, the correct answer is 7 simple bracelets and 3 deluxe bracelets, which yield an answer of 123, which is greater than 120.
