Question 3 (b) Given Sara’s age today to be y years. Think of her age in the future or in the past. What will the following expression indicate? y + 7, y – 3, y + 4 1/2 , y – 2 1/2Given, Sara’s age = y years (y + 7) years is an age larger than Sara’s age So, (y + 7) years can be Sara’s age after 7 years from now. (y − 3) years is an age smaller than Sara’s age So, (y − 3) years can be Sara’s age before 3 years from now. ("y + 4 " 𝟏/𝟐) years is an age larger than Sara’s age So, ("y + 4 " 1/2) can be Sara’s age after 4 years and 6 months from now.
