Answer:
Dylan's budget is $250, and she is buying pumpkins for $20 each and balloons for $2 each. We can represent the total cost of the pumpkins as 20x and the total cost of the balloons as 2y. The inequality that represents all possible ways she could buy pumpkins and balloons within her budget is:
20x + 2y <= 250
To find the maximum number of balloons she could buy, we can use the equation above and set x = 0, and then solve for y.
20(0) + 2y <= 250
2y <= 250
y <= 125
The maximum number of balloons she could buy is 125.
