Answer: To find out how many weeks it will take Parker to save enough money to buy the premium headphones, we need to divide the total cost of the headphones by the amount Parker saves each week.
The total cost of the headphones is $199. Parker saves $20.50 each week. So, the number of weeks (W) Parker needs to save is calculated by:
W = Total Cost / Weekly Savings W = $199 / $20.50
We can now do the division:
W ≈ 9.70731707
Since Parker can't save for a fraction of a week, we must round up to the nearest whole week. Rounding up, it will take Parker 10 weeks to save enough money to buy the headphones.
