Answer:
$439 + x ≤ $1250
x ≤ $811
Explanation:
Since Jarod can spend at most $1250 on his vacation, that means he must spend that amount or below, so when setting up the inequality the sum of his airfare and remaining money must not be higher than $1250 or ≤ $1250. Since the only thing Jarod has bought so far is airfare, his inequality is:
$439 + x ≤ $1250
Subtracting $439 from both sides: $439 + x - $439 ≤ $1250 - $439
Solve for 'x': x ≤ $811
