Can anyone help to solve the problem sum below. Thanks


6 hats and 5 belts cost $150. 5 hats and 6 belts cost $147. What is the cost of one belt?

Hi wintay here's another method, using elimination presented in a way which i think kids at P5 should be able to understand :evil:

1) Given, 6 hats and 5 belts= $150 ( mutiple all by 5)
we get... 30 belts and 25 belts= $750

2) Given also, 5 hats and 6 belts= $147 ( mutiple all by 6)
we get... 30 hats and 36 belts = $882

3) since now we know...

30 hats and 36 belts = $882
30 belts and 25 belts= $750

36- 25 belts is obviously = $882-$720
so 11 belts = $132
1 belt=$12

Hope it helps

Hi

If you’re familiar with SE, you may use it.

Otherwise, you may work using MD or letters of the alphabet.

HHHHHH (6H) + BBBBB(5B) ------- 150
HHHHH(5H) + BBBBBB(6B) ------- 147

Hence, H ----- B + 3

BBBBBB + 18 + BBBBB ------- 150

BBBBBBBBBBB(11B) + 18 ------ 150

BBBBBBBBBBB(11B) + 18 ------ 150

BBBBBBBBBBB(11B) ------ 132

B ------ 12

Best wishes

Hi Thanks. Btw what is SE? And is that the only way to solve the problem sum?
