   Zee has 17 buttons, 4 fewer than Milo. Let b be Milo's buttons. The bars show Zee's 17, a longer bar for Milo, and a gap of 4. Which equation matches the story?

   • 4 − b = 17
   • b = 17 − 4
   • 4b = 17
   • b − 4 = 17

   Bo has 15 buttons. Pia has 4 fewer than Bo. Let t be Pia's buttons. The bars show Bo's 15, a shorter bar for Pia, and a gap of 4. Which equation matches the story?

   • t = 15 + 4
   • 4t = 15
   • t = 15 − 4
   • t/4 = 15
