- Find the amount that she paid for the fruits in terms of f.
- If f = 7, how much change did Mrs Julie receive if she paid the fruit seller with a $100 note?
(a)
Amount paid for the honeydews
= 4 x
f = $4
f Amount paid for the lemons
= 2 x 2
f = $4
f Total amount paid for the fruits
= 4
f + 4
f = $8
f (b)
Amount that Mrs Julie paid for the fruits
= 8
f = 8 x 7
= $56
Amount of change that Mrs Julie received
= 100 - 56
= $44
Answer(s): (a) $8
f ; (b) $44
