8) If you take the box as A,
A + 75 oranges = 17,375 grams
A + 50 oranges = 12,000 grams
It means,
25 oranges = 17,375 - 12,000 = 5,375 grams
To find 1 orange, ( / = divide )
1 orange = 5,375 / 25 = 215 grams
50 oranges = 215 X 50 = 10,750 grams
The box will then be,
A = 12,000 - 10,750 = 1,250 grams
9) 48 curry puffs / 3 per packet = 16 packets
16 packets X $2 = $32
Remaining 2 curry puffs,
1 curry puff = $0.80
2 curry puffs = $0.80 X 2 = $1.60
$32 + $1.60 = $33.60
