To determine which inequality represents James' situation, we need to consider the earnings from oil changes and tune-ups and ensure they are greater than $\$200$.<br /><br />Given:<br />- $x$ = number of oil changes<br />- $y$ = number of tune-ups<br />- Earnings from each oil change = $\$18$<br />- Earnings from each tune-up = $\$49$<br /><br />James needs to earn over $\$200$ a day. Therefore, the total earnings from oil changes and tune-ups should be greater than $\$200$.<br /><br />The inequality representing this situation is:<br />\[ 18x + 49y > 200 \]<br /><br />So, the correct answer is:<br />B. \( 18x + 49y > 200 \)
