How many toys are there?  Choose the correct choice from the following options
A) 10 B) 20 C) 30 D) 40 E) 50
x : the total number of toys   x/10 : the number of toys for first child   x/10 + 12 : the number of toys for second child   x/10 + 1 : the number of toys for the third child   2(x/10 + 1) : the number of toys for the fourth child   x/10 + x/10 + 12 + x/10 + 1 + 2(x/10 + 1) = x   x = 30 toys : solve for x
