Final answer:
After setting up and solving an equation based on the information given, the initial number of stickers Mai gave to each volunteer is found to be 4. Therefore correct option is A
Step-by-step explanation:
To solve for y, the initial number of stickers given to each volunteer by Mai, we can set up an equation based on the information provided. Mai initially gives each volunteer y stickers and then gives two more stickers to each, in total with five volunteers, the sum is 30 stickers. Thus, the equation is 5y + 2(5) = 30.
Starting with that equation:
- 5y + 10 = 30
- Subtract 10 from both sides: 5y = 20
- Divide both sides by 5: y = 4
So the initial number of stickers given to each volunteer is y = 4.
