Bella\t\tEra + Angela\t\ttotal
1u\t\t3u\t\t\t4u x3
3\t\t9
Era\t\tBella + Angella
1\t\t5\t\t\t6ux2
2\t\t10

Angela  12 – 5 = 7u
7u – 2u = 5u
5u  $60
1u  12
12u  12 x 12 = $144

Thank you ksi for your solution, the answer is correct as given in the assessment book. However, before I checked the answer, I worked out together with dd and we simply take (303-32-15)/2. And I couldn't understand the answer given, now that I looked at yours, I just realised that we should take 32x2 instead of simply 32. Will use your model and explain to dd again.

Once again, :thankyou: for your help. :salute:

Hi barney, you are most welcome. That is the beauty of models, it makes it easy to see the units we might have left out when we compute the values. Have fun.

Can someone help me with this question?


45 blue balls and 12 green balls were put into a basket containing some blue and green balls. There were 23 more blue balls than green balls in the end. How many fewer blue balls than green balls were there in the basket at first?

Hi

45 – (23 +12) = 10

There are 10 fewer blue balls than green balls in the basket at first.

Best wishes
