Jenny, Mandy, and Sasha sold boxes of girl scout cookies.

· Mandy sold 13 more boxes than Jenny

· Sasha sold 6 less than twice as many boxes as Jenny

· Altogether they sold 115 boxes of cookies

If x represents the number of boxes of cookies that Jenny sold, which equation can be used to determine how many boxes of cookies that Jenny sold?

• x + 13 + 2x – 6 = 115

• x + 13 + 6 – 2x = 115

• x + x + 13 + 2x – 6 = 115

• x + x + 13 + 6 – 2x = 115
