Question

Carson has $450 in his bank account and deposits $70 per month out of his babysitting money. Construct a liner function that models carson bank balance for any given month

Answer 1

Remember that the linear function

`y=mx+b`

Can model a problem where

• m, is the variable term. In this case, the babysitting money

,

• b, is the fixed term. In this case, the initial deposit.

Therefore, the expression that would model the situation is:

`y=70x+450`
