- Find the amount that she paid for the fruits in terms of z.
- If z = 5, how much change did Mrs Wendy receive if she paid the fruit seller with a $100 note?
(a)
Amount paid for the honeydews
= 3 x
z = $3
z Amount paid for the tomatoes
= 4 x 2
z = $8
z Total amount paid for the fruits
= 3
z + 8
z = $11
z (b)
Amount that Mrs Wendy paid for the fruits
= 11
z = 11 x 5
= $55
Amount of change that Mrs Wendy received
= 100 - 55
= $45
