Ms. Rudow and Mrs. Dobbs really like chocolate. Mrs. Dobbs ate 6 less than twice the number of chocolate pieces that Ms. Rudow ate. Together, they ate a total of 27 pieces. Write a system of equations that models this situation if Mrs. Dobbs ate d pieces of chocolate and Ms. Rudow ate r pieces of chocolate.

• $d=2r–6$
  $d+r=27$
  

• $d=6-2r$
  $d=27-r$
  

• $r=2d-6$
  $r=27+d$
  

• $r=2d-6$
  $d+r=27$

A box contains 28 coins consisting of quarters and dimes. The total value of the coins is $4.95. Write a system of equations that can be used to determine the number of quarters, q, and the number of dimes, d, in the bag?

• $0.10q+0.25d=4.95$
  $q+d=28$
  

• $0.10q+0.25d=28$
  $q+d=4.95$
  

• $0.25q+0.10d=4.95$
  $q+d=28$
  

• $0.25q+0.10d=28$
  $q+d=4.95$
