Lets work backwards, he had $5 after it all, and spent $1.25 on a snack, so we add that to the remainder, which is $6.25. then he spent half of that on whatever stuff he likes, so add $6.25 and $6.25, which is $12.50
        
                    
             
        
        
        
Answer:
- B. The probability that the student received a grade better than C is 0.45
Step-by-step explanation:
<u>Total number of students:</u>
- 15 + 30 + 35 + 16 + 4 = 100
<h3>Statements</h3>
A. 
- p(<D) = 4/100 = 0.04
- 0.04 ≠ 0.2
- Incorrect
B. 
- p(>C) = (30 + 15)/100 = 45/100 = 0.45
- 0.45 = 0.45
- Correct
C.
- p(not A or B) = (100 - 15 - 30)/100 = 55/100 = 0.55
- 0.55 ≠ 0.45
- Incorrect
D.
- p(B or C) = (30 + 35)/100 = 65/100 = 0.65
- 0.65 ≠ 0.35
- Incorrect

 pounds of clay.
Step-by-step explanation:
Hi
a) We have to find the total amount of clay, as she needs  and
 and  , so
, so  , is the total amount of clay. Then as we Know that one bag of clay has
, is the total amount of clay. Then as we Know that one bag of clay has  , It isn´t enough, but with two bags
, It isn´t enough, but with two bags  , It is enough clay.
, It is enough clay.
b) She will have leftover  of the second bag, then we add the third one, so
 of the second bag, then we add the third one, so  are leftover.
 are leftover.
