Answer:

72 voters

Step-by-step explanation:

Total surveyed members: 40

Total members with a yes vote: 12

Percentage of the voters (voting yes): \frac{12}{40} * 100 = 30%

From analysis, it is observed that 30% of the voters are expected to vote yes in a sample.

Therefore, the number of voters expected to vote yes out of 240 are: 30% of 240

=> \frac{30}{100} * 240 = 72

Mario buys tickets for either 47 or 57 dollars. He purchases 14 tickets and spends 738 dollars. How many tickets did he purchase
Ivanshal [37]

Answer:

6 tickets were purchased at $47

8 tickets were purchased at $57

Step-by-step explanation:

Let the tickets purchased at $47 be x

Let the tickets purchased at $57 be y

We can form an equation from the question given which will be:

x + y = 14 ....... i

47x + 57y = 738 ........ ii

From equation i

x = 14 - y ........ iii

Substitute iii into ii

47x + 57y = 738

47(14-y) + 57y = 738

658 - 47y + 57y = 738

Collect like terms

-47y + 57y = 738 - 658

10y = 80

y = 80/10

y = 8

8 tickets were purchased at $57

Note that from i

x + y = 14

x + 8 = 14

x = 14 - 8

x = 6

6 tickets were purchased at $47

Susie lost $15 on Monday. Her mom was upset, but gave her another $20. She lost another $13 today. Write an integer to represent
maria [59]

Answer:

Step-by-step explanation:

If you add 13 +15 you get 28$ if we were to write that as an integer out of 20 it would be 28/20 but as an improper fraction, it would need to  be simplified into  1 and 8/20  ( 1  8/20)

If you are looking how much she lost out of the 20 she lost today it would be 13/20

Hope this helps
