- If r = 7, how much change did Mrs Jaslyn receive if she paid the fruit seller with a $100 note?
(a)
Amount paid for the avocados
= 4 x
r = $4
r Amount paid for the papayas
= 2 x 4
r = $8
r Total amount paid for the fruits
= 4
r + 8
r = $12
r (b)
Amount that Mrs Jaslyn paid for the fruits
= 12
r = 12 x 7
= $84
Amount of change that Mrs Jaslyn received
= 100 - 84
= $16
Answer(s): (a) $12
r ; (b) $16
