Hi there!
In direct substitution, simply plug in the x-value given to solve for the limit as x approaches zero:
First calculate that numeric value. It cannot be done immediately without calculations.
if 85% of studends liked mystery that means that 100% - 85% = 15% didnt like.
Those 15% are 30 that were given in text. Now we can calculate this using proportion:
15% 30 students
85% x students
we use cross multiplication:
15*x = 30*85
x = 30*85/15
x = 170
Answer is 170
