Carlos and Maria played a game of rolling two number cubes and finding the sum of the numbers. They recorded how many times each sum was
rolled in the table below.

sum frequency
2 16
3 1
4 5
5 7
6 8
7 18
8 20
9 14
10 14
11 5
12 5

Which statement is true?
A. A sum of 8 was rolled about 14% of the time.
B. A sum of 2 was rolled about 1.8% of the time.
C. A sum of 9 or 10 was rolled about 25% of the time.
D. A sum of 5 or 6 was rolled about 10.1% of the time.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
