Rita works at a music store. On Tuesday, she sold 6 more than 3 times the number of guitars that she sold on Monday. Rita sold a total of 110 guitars over the two days. Write a system of equations that can be used to find the number of guitars she sold on Monday and Tuesday. Let m = number of guitars sold on Monday and

t = number of guitars sold on Tuesday.

• m + t =9

  t = 6 + 3m

• m + t = 110

  t = 6 + 3m

• m + t = 110

  m = 6 + 3t

• m + t = 110

  t = 3m - 6
