- Find the amount that she paid for the fruits in terms of f.
- If f = 5, how much change did Mrs Hilda receive if she paid the fruit seller with a $100 note?
(a)
Amount paid for the apples
= 5 x
f = $5
f Amount paid for the durians
= 2 x 4
f = $8
f Total amount paid for the fruits
= 5
f + 8
f = $13
f (b)
Amount that Mrs Hilda paid for the fruits
= 13
f = 13 x 5
= $65
Amount of change that Mrs Hilda received
= 100 - 65
= $35
Answer(s): (a) $13
f ; (b) $35
