True Statements:

"Kaylee's necklace can have 25 pieces of rotelle"

"Kaylee's necklace can have 10 macaroni noodles and 15 pieces of rotelle"

"Kaylee's necklace can have 1 macaroni noodle"

Step-by-step explanation:

First condition:

max pieces is 25

Checking the choices, we eliminate anyone having more than 25 pieces.

choice 1 - 26 piece NO

choice 2 - 25 piece OK

choice 3 - 25 piece OK

choice 4 - 25 piece OK

choice 5 - 1 piece OK

choice 6 - 25 piece OK

So we eliminate first choice. Now, 2nd condition is 15 macaroni or 50 rotelle, so that's 50/15 = 3.33 rotelle = 1 macaroni

We check each choice and convert macaroni to rotelle and make sure they are under 50

choice 2 - 25 rotelle, so OK

choice 3 - 10*3.33 + 15 = 48.3, under 50, so OK

choice 4 - 14*3.33 + 11 = 57.62, NOT OK

choice 5 - 1*3.33 = 3.33 rotelle OK

choice 6 - 16*3.33 + 9 = 62.28 rotelle , NOT OK

So finally, the statements that are TRUE are:

Choice 2, Choice 3, Choice 5

a.
