✔ 最佳答案
1) Let X be the original prcie.X - 160 = 840
X = 840+160 = 1000
Discounted 160/1000 = 16%
2) $2.7 x X = $60
X = 60/2.7=22.22
So mum can buy 22 oranges with $0.22 left.

1.) The discount
=160/840+160 X 100%
=160/1000 X 100%
=16%
2.) 60 除 2.7
=22...6
Mum can buy 22 oranges and left $0.6 .
=160/840+160 X 100%
=160/1000 X 100%
=16%
2.) 60 除 2.7
=22...6
Mum can buy 22 oranges and left $0.6 .
