No, Althea's estimate is unreasonable
Explanations:Note:
Number of weeks in a year = 52
If Althea saves $4.50 per week
Total savings in a year = $4.50 x 52
Total savings in a year = $234
Althea wants to buy a bicycle worth $286.15 at the end of the year
By saving $4.50 each week, Althea's savings at the end of the year($234) will be less than $286.15 needed to buy the bicycle.
Therefore, Althea's estimate is unreasonable
