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.
choose the possible combination of bracelets that dimitri may have made.

a. 3 simple bracelets and 4 deluxe bracelets

c. 12 simple bracelets and 0 deluxe bracelets
d. 7 simple bracelets and 3 deluxe bracelets

Given that it takes Dimitri 9 minutes to make a simple bracelet and 20 minutes to make a deluxe bracelet.

Time taken is more than 120 minutes

x = simple bracelets and y = deluxe bracelets

Total time taken =

possible combinations would be the integral values of x and y which satisfy the above inequality

A) 3,4 substitute to check .

Hence not a solution

B) Time taken =24 hence not a solution

C) time taken 108 seconds hence cannot be solution

D)

Yes. a solution
