Let's start with the known information. There is a set value, which is $25.50. Next it was given that the rate is $1.50 per mile. Lastly, Jack does not want to spend more than $60 total. With these information, you can set up an inequality. Let x be the number of miles. 1.50x + 25.50 ≤ 60 Subtract 25.50 on both sides 1.50x ≤ 34.50 Divide both sides by 1.5 x ≤ 23 This means that the greatest number of miles Jack can drive is 23.
