Question Description

This Discussion will help us learn to develop our own mathematicalmodels, write down the equations and then solve the equations forunknown values using algebraic methods.

Refer back to Week One Discussion and use the names and ages ofyourself and the other two people you selected. Make sure one is olderthan you and one is younger than you.
In years, how old was the older person when you were born?
Write an equation that models how old in years each of you willbe, when your ages add up to 150 years old. For example, if x = yourage and the eldest person was a year older than you, you would writetheir age as x + 1. Then the equation would be: x + (x+1) = 150.
Explain the reasoning which helped you develop your equation.
Solve for your future ages. Are your answers reasonable, do they add up to 150?
In years, how old were you when the youngest person was born?
At some point during the lives of you and the youngest person, your age will be three times his/her age at that moment. Write an equation which models how old in years each of you will be when you are three times as old as the younger person.
Explain the reasoning which helped you develop your equation.
Solve the equation for your ages when you are three times as old as the youngest person. Are your answers reasonable?
Respond to at least two of your classmates’ postings. Checktheir equations and investigate for mathematical errors. Help with aconstructive critique.
