A man bought x apples and twice as many oranges. He also bought 5 pears fewer than apples. Each apple costs 40 cents, each orange cost 30 cents and each pear cost 80 cents. If the man spent a total of $77, find
(i) the value of x
(ii) the amount of money he spent on buying the pens

Hey Soon Teck,
Following is my worked solution :
(i)
A = x
O = 2x
P = (x  5)
Given each apple (A) cost 40 cents, each orange (O) cost 30 cents and each pear (P) cost 80 cents, we have ...
40x + (2x × 30) + [(x  5) × 80] = 7700
40x + 60x + 80x  400 = 7700
180x = 7700 + 400
180x = 8100
x = 45
(ii)
P = (x  5) = 45  5 = 40
Amount spent on P = 40 × 80 = 3200 = $32
=======
Trust the above helps.
Do let me know again if this is different from your <Answerkey> or if there's further clarification.
Cheers,
Edward
