Bob's age is 4 times greater than Suzan's age. Dakota is three years younger than Suzan. The sum of Bob's, Suzan's, and Dakota's age is 93. What is Suzan's age

Susan is 16 years old.

Step-by-step explanation:

Let x represent Susan's age.

Bob's age is 4 times greater than Suzan's age. This means that Bob's age is 4x.

Dakota is three years younger than Suzan. This means that Dakota's age is x - 3

The sum of Bob's, Suzan's, and Dakota's age is 93. This means that

4x + x - 3 + x = 93

4x + x + x = 93 + 3

6x = 96

x = 96/6 = 16

Bob's age = 4x = 4 × 16 = 64

Dakota's age = x - 3 = 16 - 3 = 13
