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