Question 22398
<pre>Mary is "y" years old. Her father is 4 times older than Mary. Her mother is 7
years younger than her father. If the three ages add up to 101 years, find the
value of "y". Find the ages of Mary's parents.

>>...Mary is "y" years old...<<

Translation:  Mary's age = y

>>...Her father is 4 times older than Mary...<<

Translation:  Father's age = 4y

>>...Her mother is 7 years younger than her father...<<

Transation:  Mother's age = 4y - 7

>>...the three ages add up to 101 years...<<<

Translation:  y + 4y + (4y - 7) = 101

Can you solve that for y?  If not post again

Answers: y = 12, Mary is 12, her father is 48 and her mother is 41.
