Answer the following question.
Steven's teacher sends the class an assignment to collect 60 different fruit seeds. Apples average 6 seeds, pears average 2 seeds, and grapes average 3 seeds. Steven has set aside 4 apples, 3 pears, and 9 grapes to extract their seeds. How many more seeds does he need to fulfill his assignment?
Step-by-step reasoning process: With 4 apples, Steven will collect 4 apples * 6 seeds / apple = 24 seeds. With 3 pears, Steven will collect 3 pears * 2 seeds / pear = 6 seeds. With 9 grapes, Steven will collect 9 grapes * 3 seeds / grape = 27 seeds. In total, Steven will collect 24 seeds + 6 seeds + 27 seeds = 57 seeds. To collect 60 seeds he needs 60 seeds - 57 seeds = 3 more seeds.
The answer is 3.

Answer the following question.
Laura is hosting a carwash. She will charge $5 for a car, $6 for a truck, and $7 for an SUV. They raised $100 in total. If they washed 5 SUVs and 5 trucks, how many cars did they wash?
Step-by-step reasoning process: They earned $30 from trucks because 5 x 6 = 30. They earned $35 from SUVs because 5 x 7 = 35. They earned $35 from cars because 100 - 35 - 30 = 35. They washed 7 cars because 35 / 5 = 7.
The answer is 7.
