Y=7 and
X=9
Step-by-step explanation:
X+Y=16
X=2+Y
2+Y+Y=16
2+2Y=16
2Y=16-2
2Y=14
2Y/2=14/2
Y=7
X =2+Y
So X=9

New discounted price = 1274
Let original price = p

P = 1499
Answer:
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
Step-by-step explanation:
As the test is targeted to 18-to-29-year-old adults using social media, we want to know the probability that a randomly selected adult uses social media and belong to the study group.
To achieve this, we have this data:
- 36% of all adults do not use social media
- 75% of all adults are >30 years old.
- The percentage of population that is <em>either</em> 18-29 years old <em>or</em> uses social media is 66.7%
Using the last data we have that

The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
