Verified answer

Set up a grid like this and delete options when you discover facts

Martha (AmEx, MisCh, Plat, Rec,Viva)-(Car, Hotel, Meals, Plane, Souvenir)-(Stewart,Trudo,Underwood,Vale,Williams)

Nicki (AmEx, MisCh, Plat, Rec,Viva)-(Car, Hotel, Meals, Plane, Souvenir)-(Stewart,Trudo,Underwood,Vale,Williams)

Olivia (AmEx, MisCh, Plat, Rec,Viva)-(Car, Hotel, Meals, Plane, Souvenir)-(Stewart,Trudo,Underwood,Vale,Williams)

Patty (AmEx, MisCh, Plat, Rec,Viva)-(Car, Hotel, Meals, Plane, Souvenir)-(Stewart,Trudo,Underwood,Vale,Williams)

Rhoda (AmEx, MisCh, Plat, Rec,Viva)-(Car, Hotel, Meals, Plane, Souvenir)-(Stewart, Trudo,Underwood,Vale,Williams)

Clue 3. Nicki = Stewart (delete this option from the others). Nicki not souvenirs

Clue 2. Nicki not Mistercharge as that is Williams

Clue 4. Martha and Olivia neither AmEx or Trudo

Clue 6. Rhoda not Underwood

Clue 7. Olivia = car rentals - delete thisfrom the others

Clue 8. Martha not Recovery

Clue 5. Vale = meals therefore nicki (Stewart) is not meals

Clue 9. Souvenirs = AmEx therefore Martha is not souvenirs as she can't be AmEx.

Clue 5 vale = meals therefore Olivia (car rental) can't be Vale

The grid now looks like this

Martha (MisCh, Plat,Viva)-(Hotel, Meals, Plane)-(Underwood,Vale,Williams)

Nicki (AmEx, Plat, Rec,Viva)-( Hotel,Plane)-(Stewart)

Olivia ( MisCh, Plat, Rec,Viva)-(Car Rental)-(Underwood,Williams)

Patty (AmEx, MisCh, Plat, Rec,Viva)-(Hotel, Meals, Plane, Souvenir)-(Trudo,Underwood,Vale,Williams)

Rhoda (AmEx, MisCh, Plat, Rec,Viva)-(Hotel, Meals, Plane, Souvenir)-(Trudo,Vale,Williams)

Clue 9 Souvenirs = Amex -as Nicki can't have bought souvenirs she can't have AmEx

Clue 4 Four women are Marsha, Olivia AmEx and Trudo. The only two that can be AmEx and Trudo are Patty and Rhoda. Clue 10 the Hotel is not Trudo therefore cannot be either Patti or Rhoda. One of these two women is Trudo and the other is AmEx which bought souvenirs and therefore can't be hotel

Patty and Rhoda are AmEx and Trudo therefore from Clue 2 neither can be Mister Charge or Miss Williams

Martha (MisCh, Plat,Viva)-(Hotel, Meals, Plane)-(Underwood,Vale,Williams)

Nicki ( Plat, Rec,Viva)-( Hotel,Plane)-(Stewart)

Olivia ( MisCh, Plat, Rec,Viva)-(Car Rental)-(Underwood,Williams)

Patty (AmEx Plat, Rec,Viva)-(Meals, Plane, Souvenir)-(Trudo,Underwood,Vale)

Rhoda (AmEx, Plat, Rec,Viva)-( Meals, Plane, Souvenir)-(Trudo,Vale,)

Looking at the above grid

Lets assume Rhoda = Vale, therefore clue 9 she is meals. This also means asTrudo is either Rhoda or Patty , then Patti must be Trudo, which from clue 4 means Rhoda is AmEx, but Rhoda can't be Am EX as that card bought souvenirs and Vale bought Meals. Therefore Rhoda CANNOT be Vale and therefore must be TRUDO (last option)

This makes Patty AMEX and SOUVENIRS

Clue 5 Vale bought meals, therefore Rhoda (Trudo) did not. The only woman left who could have bought the MEALS is Martha who is therefore VALE and not Viva.

Clue 2 Mistercharge is Williams therefore Martha (Vale) is not Mistercharge and has to be PLATINUM.(last option)

The only woman that can be mistercharge that is left is OLIVIA who is therefore also WILLIAMS (clue 2)

This makes Patti UNDERWOOD last name available

RHODA is PLANE TICKETS (last option available) and in turn NICKI must be the hotel.

Clue1 The plane tickets (Rhoda) were not recovery, therefore RHODA must be VIVA and NICKI must be recovery.

Final solution

Martha (Platinum)-(Meals)-(Vale)

Nicki (Recovery)-(Hotel)-(Stewart)

Olivia ( MisterCharge)-(Car Rental)-(Williams)

Patty (AmEx)-(Souvenir)-(Underwood)

Rhoda (Viva)-( Plane)-(Trudo)

this takes time, you have to go over the hints, once a hint is useless cross it out, after you went through all the hints, go again, this time with what you already know, try it. (sorry, i can't do it bc dont have much time.)

(ill try to get it)
