- If y = 5, how much change did Mrs Usha receive if she paid the fruit seller with a $50 note?
(a)
Amount paid for the pineapples
= 5 x
y = $5
y Amount paid for the avocados
= 2 x 2
y = $4
y Total amount paid for the fruits

y + 4
y = $9
y (b)

y = 9 x 5
= $45
Amount of change that Mrs Usha received
