Cost of meal = m
Tip = t
is m + t > x?
Statement 1
t = 20% of m
m+t = 1.2m
We don't know m
Insufficient
Statement 2
m = (x-10)
we do't know t
Insufficient
Combined
m+t = 1.2(x-10)
x is unknown or rather we don't know if 1.2x-12 is greater or less than x
Scenario:
1.2(x-10)>x
.2x>12
x>60
If x>60, answer is yes else no. But we don't know x. Insufficient
Answer E
Tip = t
is m + t > x?
Statement 1
t = 20% of m
m+t = 1.2m
We don't know m
Insufficient
Statement 2
m = (x-10)
we do't know t
Insufficient
Combined
m+t = 1.2(x-10)
x is unknown or rather we don't know if 1.2x-12 is greater or less than x
Scenario:
1.2(x-10)>x
.2x>12
x>60
If x>60, answer is yes else no. But we don't know x. Insufficient

Question: Did Jen spend > $x?
Statement 1:Jennifer left a tip equal to 20 percent of the cost of the meal.
Can't calculate as no information about dollars
NOT SUFFICIENT
Statement 2:(2) Jennifer's meal cost (x - 10) dollars excluding the tip.
Can't calculate as no information about dollars and the tip
NOT SUFFICIENT
Combining the statements
Meal = (x-10), Tip = 20%
Nw, if the tip is more than $10 the overall spend will exceed x or vice versa hence
NOT SUFFICIENT
Answer: Option E
