We have a question: Cynthia harvested 67 potatoes from her garden. After washing them, she cut 13 of them into wedges. She then halved the remaining potatoes and made french fries with one half, and potato chips with the other half. If one potato can be cut into 8 wedges or make 20 potato chips, how many more potato chips than wedges did Cynthia make?
And an answer: 436
So how you got the answer?
Cynthia was left with 67 - 13 = 54 potatoes after making wedges. She used 54 / 2 = 27 potatoes to make potato chips. Cynthia made 13 x 8 = 104 wedges. She made 27 x 20 = 540 potato chips. Cynthia made 540 - 104 = 436 more potato chips than wedges.

We have a question: Justice has 3 ferns, 5 palms, and 7 succulent plants in her house. If she wants a total of 24 plants in her home, how many more plants does she need?
And an answer: 9
So how you got the answer?
Justice currently has 3 + 5 + 7 = 15 plants in her house. Justice needs 24 - 15 = 9 more plants.

To make 1 lei, Jaynie will need 2.5 x 12 = 30 plumeria flowers. To make 4 leis, she will need to pick 30 x 4 = 120 plumeria flowers from the trees.
