Answer this question:Martha is making centerpieces for her Thanksgiving dinner. There are six centerpieces, and each centerpiece uses 8 roses, twice as many orchids as roses, and a certain number of lilies. If Martha wants to spend $2700 total, and each flower costs $15, how many lilies will she put in each centerpiece?
First figure out how many total flowers Martha is going to buy by dividing her total spending by the price per flower: $2700 / $15 / flower = 180 flowers. Now figure out how many flowers are in each centerpiece by dividing the total number of flowers by the number of centerpieces: 180 flowers / 6 centerpieces = 30 flowers / centerpiece. Now figure out how many orchids are in each centerpiece by multiplying the number of roses per centerpiece by 2: 8 roses / centerpiece * 2 = 16 orchids / centerpiece. Now subtract the number of roses and orchids per centerpiece from the total number of flowers per centerpiece to find the number of lilies per centerpiece: 30 flowers - 16 orchids - 8 roses = 6 lilies.
The answer is 6.

Answer this question:In a jar that has 50 ants, the number of ants in the jar doubles each hour. How many ants will be in the jar after 5 hours?
After first hour, 50 * 2 = 100 ants. After the second hour, 100 * 2 = 200 ants. After the third hour, 200 * 2 = 400 ants. After the fourth hour, 400 * 2 = 800 ants. After the fifth hour, 800 * 2 = 1600 ants.
The answer is 1600.

Answer this question:Hally and her friends organized a high school reunion. To cover the cost of a late-night party that they planned for at the reunion, each attendee had to pay $100. After the party, Hally and her friends realized that the total expenses were $500 less than the total contributions. If there were 50 people at the party, how much money was used to pay for the party expenses?
The total planned cost for the party was 100 * 50 = $5000. The total expenses for the party are 5000 - 500 = $4500.
The answer is 4500.

Answer this question:Seth and his brother want to see their favorite band in concert. The tickets are $50.00 each. There is a 15% processing fee for the tickets. They are also charged $10.00 for parking and an additional $5.00 per person entrance fee. How much will it cost to go to the concert?
The tickets are $50.00 each and they need 2 tickets so that's 50 * 2 = $100.00. There is a 15% processing fee for the tickets so that's 100 * .15 = $15.00. The tickets are $100.00 and the processing fee is $15.00 for a total of 100 + 15 = $115.00. There is a $5.00 per person entrance fee and there are 2 people so that's 5 * 2 = $10.00. The tickets are $115.00, parking is $10.00 and the entrance fee is $10.0 for a total of 115 + 10 + 10 = $135.00.
The answer is 135.
