Janet spent 2/7 of her money on 4 pencils and 8 books. She then spent the remaining amount of money on 6 pencils, 10 toys and 12 books. How many toys could she buy with 6/7 of her money?

Let the price of 1 pencil ==P

Let the price of 1 book==B

Let the price of 1 toy==T

 

4P  +  8B ==2/7,

6P  +  12B ==5/7 - 10T, solve for T

 

T ==1/35

1/35T ==6/7

T==30 - number of toys she could buy with 6/7 of her money.
