Identify Total Items: We got 3 items, right? So we just gotta figure out which price makes sense for 3 of 'em.
Calculate Total for $1: If each item was $1, then 3 items would be 3 times that, so $3. But that's not an option here.
Calculate Total for $6: Now, if each item was $6, then 3 items would be 3 times $6, which is $18. But that ain't an option either.
Calculate Total for $20: Okay, so what if each item was $20? Then 3 items would be 3 times $20, which is $60. That's way too high, not on the list.
Calculate Total for $34: Last one, if each item was $34, then 3 items would be 3 times $34, which is $102. That's definitely not it.
Combine Prices: So none of the single prices work if we just multiply by 3. We gotta mix 'em up. Let's try combining the prices to see if we can hit a total that's on the list.
Try $6 and $20: If we take two items at $6 and one item at $20, that adds up to $6+$6+$20, which is $32. That's close to one of the options, but not quite.
Try $6 and $34: What if it's one item at $6 and two items at $20? That's $6+$20+$20, which is $46. Nope, that's not it either.
Reevaluate Calculation: Let's try one item at $6 and two items at $34. That's $6+$34+$34, which is $74. That's way off.
Reevaluate Calculation: Let's try one item at $6 and two items at $34. That's $6+$34+$34, which is $74. That's way off.Wait a sec, I made a mistake. Let's go back and check the math again.
