Answer:

14 dollars

Step-by-step explanation:

Since we know that each yard of string costs 4 dollars, and that Kaylle and her mom need 3 1/2 yards of string total, we can:

- multiply 3 × 4 to get 12

Since 2 is 1/2 of 4, we can:

- add 12 + 2 = 14

3 1/2 yards of string will cost 14 dollars in total.
