Answer the following question.
The sum of Mario and Maria's ages now is 7. Mario is 1 year older than Maria. How old is Mario?
Step-by-step reasoning process: If x is Maria's age, then Mario's age is x + 1. The equation that represents the sum of their ages is x + x + 1 = 7. By combining like terms, the equation becomes 2x = 6. Hence, the value of x which represents the age of Maria is 6 / 2 = 3. So Mariu is 3 + 1 = 4 years old.
The answer is 4.

Answer the following question.
Jon's laundry machine can do 5 pounds of laundry at a time. 4 shirts weigh 1 pound and 2 pairs of pants weigh 1 pound. If he needs to wash 20 shirts and 20 pants, how many loads of laundry does he have to do?
Step-by-step reasoning process: The shirts weigh 20 / 4 = 5 pounds. The pants weigh 20 / 2 = 10 pounds. So he needs to do 10 + 5 = 15 pounds of laundry. So that would take 15 / 5 = 3 loads of laundry.
The answer is 3.
