Answer:
Explanation:
To calculate how many hours you need to work to earn enough money for a $1,650 laptop computer plus the 6% sales tax, you can set up the following model:
Total cost = Cost of laptop + Sales tax
First, calculate the sales tax:
Sales tax = 6% of Cost of laptop
Sales tax = 0.06 * $1,650
Sales tax = $99
Now, add the sales tax to the cost of the laptop to find the total cost:
Total cost = $1,650 + $99
Total cost = $1,749
Now, you want to earn this total cost by working at a rate of $16.50 per hour. To find the number of hours you need to work, you can use the formula:
Number of hours = Total cost / Hourly rate
Number of hours = $1,749 / $16.50 per hour
Number of hours ≈ 105.82 hours
You would need to work approximately 105.82 hours to earn enough money to purchase the laptop and cover the 6% sales tax. Since you cannot work a fraction of an hour, you would likely need to work 106 hours to have enough money to buy the laptop.
