Please help with working solution
5) Mr Lim had two identical vases for sale at his shop. The price of each vase was $450. He sold one vase at this price and earned 20% of what he paid for it. He sold the other vase at a 5% discount. How much did Mr Lim earn altogether? (Hint : What is the amount Mr Lim paid for each vase?)
Appreciate for your help.

Hey Jessica,
Solution:
Since Mr Lim earned 20% from the 1st vase,
120% > $450
(Note: Default percentage is always 100%.)
1% > $3.75
Mr Lim sells the second vase at a discount of 5%.
(Each vase is $450 = 120%)
120%5%=115% (discounted price of vase)
115% > $431.25
Total amount earned:
$431.25 + $450 = $881.25
Tell me if the answer is different from yours.

Hey Jessica,
Following is my worked solution:
(vase1)
120% = 450
100% = (450 / 120) × 100 = 375 (CP)
Amt earned (1st vase) = 450  375 = 75
(vase2)
100% = 450
95% = (450 / 100) × 95 = 427.50 (SP of 2nd vase)
Amt earned (2nd Vase) = 427.50  375 = 52.50
Total amt earned = 75 + 52.50 = $127.50
=============
Trust this helps.
Do let me know again if this does not match your Answerkey or if there's further clarification.
Cheers,
Edward

Hey <achieve_goal>,
Following are my comments to your solution:
(i) Cost Price (CP) of vase was not calculated.
(ii) 5% discount of vase2 = (5 / 100) × 450 = 22.50
Hence, Selling price (SP) of vase2 = 450  22.50 = $427.50 {not $431.25}
(iii) Amount earned = Profit.
But what was calculated in your solution was total amount sold.
Trust this clarifies.
Best Regards,
Edward
