Answer:
A person in a group where 5 people are sharing 3 small bags of snickers
Step-by-step explanation:
Let the number of calories in one bag of snickers =x
Number of calories in 3 small bags of snickers =3x
- If 5 people share 3 small bags of snickers, 1 person's share

Number of calories in 2 small bags of snickers =2x
- If 7 people share 2 small bags of snickers, 1 person's share

We then compare the two.
Let x=1

Therefore, a person in a group where 5 people are sharing 3 small bags of snickers gets more calories.
A. Erica gets 6 dollars per hour.
B. She would get 48 dollars for 8 hours.
C. I would say 5 and a half hours. Maybe 5 hours and 45 minutes.
Answer is a= 51/7 or 7 2/7
Step by step
-2/3 (a + 3) = 5/3a - 19
Distribute to resolve parentheses
-2/3a -2 = 5/3a - 19
Now to move variables to one side
Add 2/3a to both sides
-2/3a + 2/3a -2 = 5/3a + 2/3a -19
Combine like terms
-2 = 7/3a -19
Add 19 to both sides to isolate variable
-2 +19 = 7/3a -19 + 19
17 = 7/3a
Divide both sides by 7/3 to solve for a
(Remember when you divide a fraction, flip it and multiply.)
17 * 3/7 = a
51/7 = a
