Answer: Each bag was $6.00 but was marked down 75% for clearance so that's 6 * .75 = $4.50 discount. Each bag was $6.00 and there is a $4.50 discount so each bag is 6 - 4.50 = $1.50. Each bag was marked down to $1.50 a bag and she bought 2 bags for a total of 1.5 * 2 = $3.00. The answer is 3.
Q: Debra is the host of a country music radio show, and she broadcasts interviews with celebrity country music singers. Each week, she interviews three singers, one at a time. The first interview segment is always twice as long as the other two segments combined, and the third interview segment is always half as long as the second. If the third segment is 10 minutes long, how many minutes long is the entire show?
A:
If the third segment is half as long as the second, then the second segment is twice as long as the third, or 10 * 2 = 20 minutes long. The first segment is twice as long as the other two combined, or 2 * (10 + 20) = 60 minutes. Thus, in total, the show is 10 + 20 + 60 = 90 minutes long. The answer is 90.
