Question

Tom, Dorothy, and Sammy went on a vacation and agreed to split the costs evenly. During their trip Tom paid 105, Dorothy paid 125, and Sammy paid $175. In order to share the costs equally, Tom gave Sammy t dollars, and Dorothy gave Sammy d dollars. What is t-d?

Accepted Answer

Simply write down two algebraic equations. We know that Tom gave t dollars and Dorothy gave d dollars. In addition, Tom originally paid 105 dollars and Dorothy paid 125 dollars originally. Since they all pay the same amount, we have: 105 + t = 125 + d. Rearranging, we have t-d = 20. Solution 2018 RandomPieKevin. All Rights Reserved. skrrt...
