Final answer:
The inequalities that are among the constraints for this situation are: x ≥ 20 and 25x+8y ≤ 600.
Step-by-step explanation:
The inequalities that are among the constraints for this situation are:
x ≥ 20 - Ryan must purchase at least 20 blankets.
25x+8y ≤ 600 - Ryan can spend at most $600.
y ≥ 20 - There is no specific information given about the minimum number of pillows, so this inequality is not among the constraints.
x, y > 0 - Since Ryan must purchase new pillows and blankets, the number of pillows and blankets must be greater than zero.
So, the correct inequalities among the constraints are:
x ≥ 20 and 25x+8y ≤ 600.
