Answer:
1. False
2. True
3. True
4. True
5. False
Step-by-step explanation:
1. False - they sell 3 cases in 20 min as shown in the table
2. True - If they sold 3 cases in 20 min and 6 cases in 40 min, then they would sell 9 cases in an hour, and 12 cases in 1 hour and 20 min
3. True - Building off of our answer in 2, student council would have sold 15 cases in 1 hour and 40 min, and 18 in 2 hours
4. True - In 40 min, student council sold 6 cases, and in 2 hours, 18 cases, so in 2 hours and 40 min, they would have sold 24 cases
5. False - In one hour - 9 cases. In 2 hours - 18 cases. In 3 hours - 27. And in 20 min - 3 cases, so they would sell 30 cases in 3 hours and 20 min.
Answer:
A) True
B) True
C) True
D) True
E) False
Step-by-step explanation:
We are given the following information in the question.
Cases sold: 3 6
Time(min): 20 40
Thus, from the above information we can say that 3 cases are sold in every 20 minutes.
Formula:
[tex]\text{Cases sold} = \frac{\text{Total time}}{20}\times 3[/tex]
A) There are 180 minutes in 3 hours.
Cases sold = [tex]\frac{180}{20}\times 3 = 27[/tex]
Hence, the statement is true.
B) There are 80 minutes in 1 hour 20 minutes.
Cases sold = [tex]\frac{80}{20}\times 3 = 12[/tex]
Hence, the statement is true.
C) There are 120 minutes in 2 hour.
Cases sold = [tex]\frac{120}{20}\times 3 = 18[/tex]
Hence, the statement is true.
D) There are 160 minutes in 2 hour 40 minutes.
Cases sold = [tex]\frac{160}{20}\times 3 = 24[/tex]
Hence, the statement is true.
E) There are 200 minutes in 3 hour 20 minutes.
Cases sold = [tex]\frac{200}{20}\times 3 = 30[/tex]
Hence, the statement is false.
