Math Help - Finding combinations

1. Finding combinations

Meredith, Johnathan, and Roberto each have a different report to write. One report is for calculus, one is for physics, and one is for English. The reports are due next week on three different days - Tuesday, Wednesday, and Friday. Meredith's report is due before Roberto's, but after the physics report. Roberto is NOT writing a report for calculus. For which course and on what day is Meredith's report due?

How can I show that it is a Calculus report and due on Wednesday?

Hello, i'm assuming you just need a word answer (and you peeked to know the answer).
Well, first tackle Roberto. We know he is not doing calculus, nor physics since it is on a different due date. Therefore we know it is english the poor guy needs to write.
Meredith's assignment is clearly in the middle, so Roberto's is the last day, Friday.
We also know Meredith isn't doing physics either so it must be Jonathan's paper, which is the first day, Tuesday.
So what is left is calculus for Meredith, on Wednesday.

Hello, donnagirl!

Meredith, Johnathan, and Roberto each have a different report to write.
One report is for calculus, one is for physics, and one is for English.
The reports are due next week on three different days: Tuesday, Wednesday, and Friday.

(1) Meredith's report is due before Roberto's, but after the physics report.
(2) Roberto is NOT writing a report for calculus.

For which course and on what day is Meredith's report due?

From statement (1), we have: . $\boxed{\begin{array}{c}\text{Tues.} \\ \text{physics}\end{array}} \quad\Rightarrow\quad \boxed{\begin{array}{c}\text{Wed.} \\ \text{Meredith} \end{array}} \quad\Rightarrow\quad \boxed{\begin{array}{c}\text{Fri.} \\ \text{Roberto} \end{array}}$

Statement (2) says Roberto is NOT writing a calculus report.

Therefore, Meredith's calculus report is due on Wednesday.
