Thank you for your question!
In order to get the cost of 1 kg of cabbage, divide the cost by the quantity:
1.20/2.5
0.48
Now, multiply the amount for 1 kg to 3.75, because you need 3.75 times the amount.
0.48 * 3.75
1.80
So, it would cost 1.80 pounds for 3.75 kg.
Hope this helped!
No, Aileen's mom is incorrect. Aileen can read 30 pages in the same time period as her friend reads 20 pages.
To get this answer, you multiply 20 by 1.5
20 x 1.5 = 30

Answer : Area = 277.45cm^2
