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

old question but will respond so this can be closed

for each answer choice, simply plug in x = # of simple bracelets and y = # of delux bracelets into the inequality and see if it's true or not. for example, for answer choice 1, let x = 3, y = 4, and plug into 9x + 20y > 120 to see if the left side is still greater than the right side. repeat with the other choices as needed.
