E. g + ( 1/3g - 12)

Answer 1

Answer: C. $4(\dfrac13g-3)$

Step-by-step explanation:

Given: Robin braided g inches of a friendship bracelet.

Number of inches braided by Olivia = $\dfrac13g-12$

The total number of inches braided by Robin and Olivia = Number of inches braided by  Robin + Number of inches braided by Olivia

$=g+\dfrac13g-12\\\\=\dfrac43g-12\\\\\=4(\dfrac13g-3)$

The total number of inches braided by Robin and Olivia = $4(\dfrac13g-3)$

Hence, C. is the correct option.
