Answer the following question.
Wendy's truck has a gas tank that can hold 20 gallons. She also has a car with a gas tank that holds 12 gallons. The truck's tank is half full. The car's tank is 1/3 full. If she fills them both up completely, how many gallons does she add?
Step-by-step reasoning process: The truck tank has 10 gallons in it because 20 x .5 = 10. The car tank has 4 gallons in it because 12 x (1 / 3) = 4. She needs to add 10 gallons to the truck because 20 - 10 = 10. She needs to add 8 gallons to the car because 12 - 4 = 8. She needs to add 18 gallons in total because 10 + 8 = 18.
The answer is 18.

Answer the following question.
There are 10 rows of 15 chairs set up for the award ceremony. The first row is reserved for the awardees while the second and third rows are for the administrators and teachers. The last two rows are then reserved for the parents and the rest of the rows are for the students. If only 4/5 of the seats reserved for the students are occupied, how many vacant seats from the students can be given to the parents?
Step-by-step reasoning process: There are 1 + 2 + 2 = 5 rows that are not reserved for the students. Hence, 10 - 5 = 5 rows are reserved for the students. That is equal to 5 x 15 = 75 seats. But only 75 x 4 / 5 = 60 seats are occupied by the students. Therefore, 75 - 60 = 15 seats can be given to the parents.
The answer is 15.
