Joey's age is five years less than Cora's age. The sum of twice Joey's age and thrice Cora's age is at most 25. How old is Cora?
Cora = x years old
Joey = x-5 years old
The sum: write inequality as you read the problem
2(x-5) + 3x <= 25
Solve it
2x - 10 + 3x <= 25
2x + 3x <= 25 + 10
5x <= 35
x <= 35/5 = 7.
ANSWER. Cora is at most 7 years old.
