Answer the following question.
Emily just purchased 2 pairs of curtains for $30.00 each and 9 wall prints at $15.00 each. The store also offers an installation service. For $50.00 they will come to your house and professionally hang your curtains and prints. If Emily agrees to this service, how much will her entire order cost?
Step-by-step reasoning process: She buys 2 pair of curtains for $30.00 each so that's 2 * 30 = $60.00. She buys 9 wall prints at $15.00 each so that's 9 * 15 = $135.00. The curtains cost $60.00, the prints are $135.00 and the installation service is $50.00 for a total of 60 + 135 + 50 = $245.00.
The answer is 245.

Answer the following question.
A church has 100 members who've volunteered to bake cookies for the homeless in their local town. If each member baked 10 sheets of cookies, and each sheet has 16 cookies, calculate the total number of cookies the church members baked?
Step-by-step reasoning process: A sheet has 16 cookies, so if each church member baked 10 sheets, they each baked 10 sheets / person * 16 cookies / sheet = 160 cookies / person. The total number of church members who decided to volunteer is 100, so in total, they baked 160 cookies / person * 100 people = 16000 cookies.
The answer is 16000.

Answer the following question.
Juvy has a garden that has 20 rows with 10 plants in each row. She plants parsley in the first 3 rows and rosemary in the last two rows. The rest of the rows will be planted with chives. How many chives will Juvy plant?
Step-by-step reasoning process: Juvy planted 3 + 2 = 5 rows with parsley and rosemary. So, 20 - 5 = 15 rows will be planted with chives. Therefore, 15 x 10 = 150 chives will be planted.
The answer is 150.

The answer is 23.
