Answer:
We have 20 category Questions split into 5
Where we would assume that the 3rd question is simply 1/4 + 5/20 chance.
This is not a determiner as Robin is asked more questions.
So it is simply 1/4 and kept to factors that Robin will answer one of the 4 choices upon the 3rd question as 1/4 regardless of other questions being asked. Where Robins first answer would be the third question we subtract 4/5 = 16/20 - 5/20= 11/40. Which can only be rounded down to 2 decimal places 0.275

Answer:
13 months
Step-by-step explanation:
x is the number of months
first phone: 
f(x) = 55x + 100
second phone: 
g(x) = 51x + 150
now set up the inequality
g(x)<f(x)
51x + 150 < 55x + 100
Solve the inequality: 
51x + 150 < 55x + 100
(get everything on the correct sides... combine the like terms)
51x - 55x < 100 - 150
-4x < -50
divide both sides by -4 (don't forget to flip the inequality sign when dividing by a negative number.)
x > 50/4
x > 12.5
round up to 13
