- Find the amount that she paid for the fruits in terms of y.
- If y = 6, how much change did Mrs Zoe receive if she paid the fruit seller with a $100 note?
(a)
Amount paid for the pineapples
= 5 x
y = $5
y Amount paid for the lemons
= 2 x 2
y = $4
y Total amount paid for the fruits
= 5
y + 4
y = $9
y (b)
Amount that Mrs Zoe paid for the fruits
= 9
y = 9 x 6
= $54
Amount of change that Mrs Zoe received
= 100 - 54
= $46
Answer(s): (a) $9
y ; (b) $46
