Let "b" be the Ben's age. Then Amy's age is (b+1) years. From the condition, we have this compound inequality 33 < b + (b+1) < 45 Simplify and solve for b 33 < 2b + 1 < 45. Subtract 1 from all three terms 32 < 2b < 44. Divide by 2 all the terms 16 < b < 22. It is the ANSWER to the problem's question.
