- Find the amount that she paid for the fruits in terms of f.
- If f = 5, how much change did Mrs Tina receive if she paid the fruit seller with a $100 note?
(a)
Amount paid for the papayas
= 5 x
f = $5
f Amount paid for the pineapples
= 3 x 2
f = $6
f Total amount paid for the fruits
= 5
f + 6
f = $11
f (b)
Amount that Mrs Tina paid for the fruits
= 11
f = 11 x 5
= $55
Amount of change that Mrs Tina received
= 100 - 55
= $45
Answer(s): (a) $11
f ; (b) $45
