If Larissa earns $500 per week, she will need $250 more in order for her to reach the desired salary of $750 per week.
I am afraid you are lacking some information in the question, since you didn't specify the percentage of the commission Larissa is permitted to take, but for the sake of helping you understand the structure of this question, I will make it 100% - all of the sales money go to Larissa.
If that's true, Larissa will only need to sell enough stuff for $250.
If the commission was 50%, Larissa would have to sell enough stuff for $500 since 50% of her sales are taken.

I hope this helped you, and feel free to re-ask me this question when you have all of the information required.

Step-by-step explanation:
Really, we don't need to use that much math--we can use logic instead. Since the two congruent sides must be longer than 30in, the total has to be greater than 60in (the longest side plus the congruent sides.) So for our answer, we want the smallest total that is above sixty, which in this case is 72.44in.
Hope I helped, and let me know if you have any questions :) I can explain the real math if you want, it was just unnecessary here.
