Question 355154
HI,
Let x be the total movies shown that month
.
question states
x/2 were comedies
.
Of the "remaining" half
{{{Dramas =(2/3)(x/2)}}} and 20 were thrillers
.
{{{(x/2)= (2/3)(x/2) + 20}}}
.
simplify and solve
{{{(x/2)= (x/3) + 20}}}
.
multiplying thru with 6
{{{ 3x = (2x) + 120}}}
x = 120
.
check your answer
60 comedies  + 40 Dramas + 20 thrillers = 120 movies that month
