Hi <geniuskids>,

Following are my worked solutions:

Q1.


C + W = 320

Each of them was supposed to pay $160 in the end. {320 รท 2 = 160}

Given that W owed C $6.40 in the end, the following is what C and W paid for 2 different expenses at first.

C paid:
160 + 6.40 = $166.40

W paid:
160 - 6.40 = $153.60

From pie chart,
Food = 40% = $128
Lodging = 30% = $96
Souvenirs = 12% = $38.40
Transport = 18% = $57.60

Matching these numbers, we have ...

C paid for Food and Lodging {128 + 38.40 = $166.40}

W paid for Souvenirs and Transport {96 + 57.60 = $153.60}

Hence, W (Wendy) paid for Souvenirs at first.

==========

Q2.

Refer to attached.

==========

Trust this helps.

Do let me know again if this is different from your <Answerkey> or if there's further clarification.

Much appreciated if you can also provide the <Answerkey> for verification reason, where possible. Thank you.

Cheers,
Edward

Hi Edward,

Thank you for your help. I understand and managed to solve Q1 using yr method but still can't figure out Q2. Your answer is correct, maybe I was too tired. Will try again.
