[Question]The total for the sum and product of Elvie's age and Arielle's age are 131. If Elvie's age is 10, how old is Arielle?
[Answer]Let's say Arielle's age is x. The sum of Elvie's age and Arielle's age is 10 + x. The product of their ages is 10 * x. The total for the sum and product of their ages is 10 + x + 10 * x = 131. To find Ariel's age, we evaluate x, which is 10 + 11x = 131. This gives us a total of 11x = 121. Arielle's age is x = 121 / 11. The value of x, which is Arielles's age, is 11. The answer is 11.
