Question 1206829
<br>
Her first purchase of 4 dolls and 8 books cost her 2/7 of her money.<br>
In her second purchase, she bought 6 dolls and 12 books.  6 dolls is 3/2 of 4 dolls, and 12 books is 3/2 of 8 books, so what she spent on dolls and books in the second purchase was 3/2 of what she spent on them in her first purchase.<br>
3/2 of 2/7 is 3/7, so she spent 3/7 of her money on dolls and books in the second purchase.<br>
Together in her two purchases she spent 2/7 + 3/7 = 5/7 of her money on dolls and books.  Since she spent all her money, she spent 2/7 of her money on the 10 toys.<br>
6/7 of her money is 3 times as much as 2/7 of her money.  If she can buy 10 toys with 2/7 of her money, then she can buy 3*10 = 30 toys with 6/7 of her money.<br>
ANSWER: 30<br>
