The possible solution to the inequality is 5 number of drinks and 9 number of pretzels.

Let x represent the number of drinks purchased and y represent the number of pretzels purchased.

Jason has $65 to spend, hence:

4x + 5y ≤ 65    (1)

He must buy at least 14 drinks and pretzels altogether, hence:

x + y ≥ 14   (2)

Plotting equations 1 and 2 on geogebra online graphing tool, the possible solution is (5, 9).
