So, how old is Mrs. Jenny now if the sum of their present ages is 70 years? and how old is Mike and Ally now if the sum of their present ages is 20 years? Answer it with the step too!

Answer 1

Answer:

Joey is 20 years younger than Becky. In two years, Becky will be twice as old as Joey. Fill in the age problem chart, but do not solve.

The first sentence tells us that Joey is 20 years younger than Becky (this is the current age)

The second sentence tells us two things:

The age change for both Joey and Becky is plus two years

In two years, Becky will be twice the age of Joey in two years

Person or Object Current Age Age Change (+2)

Joey (J) B − 20 B − 20 + 2

B − 18

Becky (B) B B = 2

Using this last statement gives us the equation to solve:

B + 2 = 2 ( B − 18)
