- Find the amount that she paid for the fruits in terms of f.
- If f = 6, how much change did Mrs Barbara receive if she paid the fruit seller with a $100 note?
(a)
Amount paid for the apples
= 3 x
f = $3
f Amount paid for the papayas
= 2 x 4
f = $8
f Total amount paid for the fruits
= 3
f + 8
f = $11
f (b)
Amount that Mrs Barbara paid for the fruits
= 11
f = 11 x 6
= $66
Amount of change that Mrs Barbara received
= 100 - 66
= $34
Answer(s): (a) $11
f ; (b) $34
