Q: Viviana has five more chocolate chips than Susana, while Susana has 3/4 as many vanilla chips as Viviana. If Viviana has 20 Vanilla chips and Susana 25 chocolate chips, calculate the total number of chips they have together.
A: Viviana has 20 Vanilla chips. Susana has 25 chocolate chips. Viviana has 25 + 5 = 30 chocolate chips. Susana has 3 / 4 * 20 = 15 Vanilla chips. They have 30 + 25 = 55 chocolate chips together. Together they have 20 + 15 = 35 vanilla chips. Together they have 35 + 55 = 90 chips. The answer is 90.

Q: Three years from now, Tully will be twice as old as Kate. How old was Tully a year ago if Kate is now 29 years old?
A: Three years from now, Kate will be 29 years + 3 years = 32 years old. So by that time, Tully will be 32 years x 2 = 64 years old. This means, Tully is 64 years - 3 years = 61 years old now. Therefore, Tully was 61 years - 1 year = 60 years old last year. The answer is 60.

Q: Fernanda purchased six audiobooks from Audible to listen to from her audible app. If each audiobook was 30 hours long and she listened to 2 hours of an audiobook each day, calculate the total time it took her to finish the six audiobooks?
A:
To finish an audiobook 30 hours long, listening to 2 hours of each audiobook a day, Fernanda took 30 hours / 2 hours / day = 15 days to finish one audiobook. If she purchased 6 audiobooks, the total number of days she will take to finish all the audiobooks is 6 audiobooks * 15 days / audiobook = 90 days. The answer is 90.
