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

Answer 1

Answer: C.
`4(\frac13g-3)`

Explanation:

Given: Robin braided g inches of a friendship bracelet.

Number of inches braided by Olivia =
`\frac13g-12`

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

`=g+\frac13g-12\\\\=\frac43g-12\\\\\=4(\frac13g-3)`

The total number of inches braided by Robin and Olivia =
`4(\frac13g-3)`

Hence, C. is the correct option.
