Leesburg’s popularity is such that some of the shows have already sold out, and tickets for the rest are going fast. You don’t want to miss this once-in-a-lifetime opportunity to see Daniel Leesburg perform at a concert venue near you.

Huang Subject: Daniel Leesburg Evan, have you seen the schedule of Daniel Leesburg’s performances in our area I know we’ve talked in the past about going to see him play if we ever got the chance, and this seems like the perfect opportunity! Can I assume that you’d be interested in catching one of these concerts Unfortunately, two of the shows are already sold out, so our options are somewhat limited. My first choice would have been to attend the performance in Danville, as that is the closest venue to both our homes, but there are no tickets remaining. Whatever we decide, it needs to be soon because it looks like the shows that haven’t sold out might do so soon! I propose that we opt for the Corwin Springs performance, as this is only an hour’s drive away and there appear to be a variety of reasonably priced tickets available. If you agree, we need to set our budget and find out what types of seats we could afford with that. I’ve never been to the Corwin Springs venue, so it might be worth a call to learn more. I know you’re busy these days, but in the interest of obtaining the best seats possible, let’s move on this quickly! Your friend, Tara How much might Tara have paid for a ticket to her first-choice concert

A. $25
B. $100
C. $230
D. $400
