Susie is 5 times the age the she was twenty years ago. How old is she now?

100 yrs old

Step-by-step explanation:

20 times 5

Susie is 25 years old

Step-by-step explanation:

Let

x = the age Susie has now. x - 20 = the age she was 20 years ago.

If Susie is 5 times the age she was twenty years ago, then

x = 5. (x - 20)

x = 5x - 100

4x = 100

x = 25

Susie is 25 years old, which is 5 times the age she was 20 years ago (25 years - 20 years = 5 years).
