M + $12 = B

5M + $60 = 5B

therefore 2M + (5M + $60) = $110

7M = $50

M = $7 1/7

B = $19 1/7

You can draw the following models:
M + 12
M + 12
M + 12
M + 12
M + 12
M
M

So 7M + (5*12) = $110
so M = 50/7
There a magazine costs $50/7=$7 1/7 while a book costs $(50/7 + 12)=$19 1/7

You should check the numbers in the question. The answer looks strange.

Ya, normally where got this kind of answer with $7 1/7 leh. Especially when you convert into exact numbers of cents,how can have 14.29 cents one lor? It is like if an answer is 1.43 chicken. U know what I mean. I'm very sure the question got problem one lah. Otherwise it is a very simple question to solve. :?

[Cheerfuldad]

Q 1. Twice a number is greater than 3/5 of the number by 21. What is 2/3 of the number?


Q2. Aifangpi ans Sashimi had an equal amount of money. Each day, Aifangpi spent $60 and Sashimi spent $32. When Aifangpi has spent all her money. Sashimi still had $336 left. How much money had Aifangpi at first?

TIA
