### Complexity=5, Mode=Type A

Solve the following age problems.
1Peter is 58 years old.
The sum of the ages of Peter and Steven is 69.
How old is Steven?
Solution
Peter = 58
Peter + Steven = 69
58 + Steven = 69
Steven = 69 - 58 = 11
2Cindy is 20 years old.
The sum of the ages of Cindy and Jose is 74.
How old is Jose?
Solution
Cindy = 20
Cindy + Jose = 74
20 + Jose = 74
Jose = 74 - 20 = 54

### Complexity=5, Mode=Type B

Solve the following age problems.
14 years from now Mary will be 14 years old.
The current sum of the ages of Mary and Steven is 52.
How old is Steven right now?
Solution
Mary + 4 = 14
Mary = 14 - 4 = 10
Mary + Steven = 52
10 + Steven = 52
Steven = 52 - 10 = 42
28 years from now Peter will be 16 years old.
The current sum of the ages of Peter and Tiffany is 29.
How old is Tiffany right now?
Solution
Peter + 8 = 16
Peter = 16 - 8 = 8
Peter + Tiffany = 29
8 + Tiffany = 29
Tiffany = 29 - 8 = 21

### Complexity=5, Mode=Type C

Solve the following age problems.
13 years from now Paul will be 63 years old.
In 12 years, the sum of the ages of Paul and Jennifer will be 99.
How old is Jennifer right now?
Solution
Paul + 3 = 63
Paul = 63 - 3 = 60
(Paul + 12) + (Jennifer + 12) = 99
(60 + 12) + (Jennifer + 12) = 99
Jennifer + 84 = 99
Jennifer = 99 - 84 = 15
26 years from now Jennifer will be 50 years old.
In 5 years, the sum of the ages of Jennifer and Maria will be 96.
How old is Maria right now?
Solution
Jennifer + 6 = 50
Jennifer = 50 - 6 = 44
(Jennifer + 5) + (Maria + 5) = 96
(44 + 5) + (Maria + 5) = 96
Maria + 54 = 96
Maria = 96 - 54 = 42

### Complexity=5, Mode=Type D

Solve the following age problems.
112 years from now Maria will be twice as old as Steven.
The current sum of the ages of Maria and Steven is 36.
How old is Steven right now?
Solution
Maria + 12 = 2 × (Steven + 12)
Maria + Steven = 36
Maria = 36 - Steven
36 - Steven + 12 = 2 × (Steven + 12)
48 - Steven = 2 × Steven + 24
48 = 3 × Steven + 24
3 × Steven = 48 - 24 = 24
Steven = 8
216 years from now Peter will be twice as old as Paul.
The current sum of the ages of Peter and Paul is 4.
How old is Paul right now?
Solution
Peter + 16 = 2 × (Paul + 16)
Peter + Paul = 4
Peter = 4 - Paul
4 - Paul + 16 = 2 × (Paul + 16)
20 - Paul = 2 × Paul + 32
20 = 3 × Paul + 32
3 × Paul = 20 - 32 = -12
Paul = -4

### Complexity=5

Solve the following age problems.
15 years from now Paul will be 65 years old.
In 14 years, the sum of the ages of Paul and Mary will be 137.
How old is Mary right now?
Solution
Paul + 5 = 65
Paul = 65 - 5 = 60
(Paul + 14) + (Mary + 14) = 137
(60 + 14) + (Mary + 14) = 137
Mary + 88 = 137
Mary = 137 - 88 = 49
