Question: The epic poem currently contains 24 lines. If a person adds 3 lines to the poem every month, in how many months will the poem contain 90 lines?
Answer with step-by-step thinking: If the epic poem currently contains 24 lines, the total number of lines added for it to reach 90 is 90 - 24 = 66 lines. If a person adds 3 lines to the poem every month, it will take 66 / 3 = 22 months for the poem to contain 90 lines.
So the answer is 22.


Question: Cassidy collects movie posters from newly released sci-fi movies. After this summer, she will have six more posters in her collection, making it double the size it was two years ago when she had 14 posters. How many posters does she have now?
Answer with step-by-step thinking: Let C be the number of posters Cassidy has now. After this summer, she will have twice as many posters as when she had 14, so she will have C + 6 = 2 * 14 = 28 posters. Thus, Cassidy has C = 28 - 6 = 22 posters now.
So the answer is 22.


Question: Charlie owns one flute, two horns, and a harp. Carli owns twice as many flutes as Charlie, half as many horns as Charlie, but no harps. What is the combined total number of musical instruments owned by Charlie and Carli?
Answer with step-by-step thinking:
Charlie owns one flute, two horns, and a harp for a total of 1 + 2 + 1 = 4 instruments. Twice as many flutes as Charlie is 2 * 1 = 2 flutes,. Half as many horns as Charlie is 2 / 2 = 1 horn. Thus, Carli owns 2 + 1 = 3 instruments. Therefore, the combined total number of musical instruments owned by Charlie and Carli is 4 + 3 = 7 instruments.
So the answer is 7.
