mrs.Goh bought 4 bags of rice at $5.28 per bag ,5 packets of biscuits at $1.25 per packet and 2.8 kg of meat at $7.40 kg per kg.Assuming that GST was absorbed by the retailer,calculate the total amount she spent ?
What would be change if she paid for all these with a $5o-note?
$5.28 x 4 = ??
$5.28/bag x 4 bags = ??
$1.25/packet x 5 packets = ??
$7.40/kg x 2.8 kg = ??
Now add all together to obtain the total cost, then subtract from $50. The difference is the change returned to Mrs. Goh.

$21.12
To calculate the total amount spent by Mrs. Goh, we need to calculate the cost of each item separately and then add them up.
Calculating the cost of rice:
Mrs. Goh bought 4 bags of rice at $5.28 per bag, so the cost of rice would be 4 x $5.28 = $21.12.
Calculating the cost of biscuits:
Mrs. Goh bought 5 packets of biscuits at $1.25 per packet, so the cost of biscuits would be 5 x $1.25 = $6.25.
Calculating the cost of meat:
Mrs. Goh bought 2.8 kg of meat at $7.40 per kg, so the cost of meat would be 2.8 x $7.40 = $20.72.
Total amount spent:
To calculate the total amount spent, we need to add the costs of the individual items together:
$21.12 (rice) + $6.25 (biscuits) + $20.72 (meat) = $47.09.
Therefore, Mrs. Goh spent a total of $47.09.
Now, to calculate the change if she paid with a $50 note, we need to subtract the total amount spent from the amount she paid.
Change:
Amount paid = $50
Total amount spent = $47.09
To find the change, we subtract the total amount spent from the amount paid:
$50 - $47.09 = $2.91.
Therefore, if Mrs. Goh paid for all these items with a $50 note, she would receive $2.91 in change.
