Final answer:
To represent Chelsea's situation, we should use the inequality 3.75 + 0.65m ≤ 20. Chelsea can travel a maximum of 25 miles without going over her budget.
Step-by-step explanation:
To represent Chelsea's situation, we can use the inequality:
3.75 + 0.65m ≤ 20
where m represents the number of miles Chelsea can travel. To find the maximum number of miles Chelsea can travel without going over her budget, we need to solve this inequality for m:
0.65m ≤ 20 - 3.75
0.65m ≤ 16.25
m ≤ 16.25 / 0.65
m ≤ 25
Therefore, Chelsea can travel a maximum of 25 miles without going over her budget.
