Question

I want to buy a car for $17,500 and I make 13 an hour roughly how long would it take me to reach my goal? & how many hours would i have to work ?

Answer 1

• Cost of car=$17500
• Earnings per hour =13

Total hours

• Cost/Earnings
• 17500/13
• 1346.15

Round to the next whole instead of nearest whole to avoid depicit

• 1347 hours you have to work atleast

In most of the countries the average working hours per week is

• 45 hours

Total weeks

• 1347/45
• 29.9
• 30weeks you have to work if you don't spend any money of it

Answer 2

1347 hours

Explanation:

Assuming the income is net income (total after taxes etc.):

• Cost of car = $17,500
• Net income = $13 per hour

To calculate the number of hours to be worked to save enough to buy the car, divide the cost of the car by hourly net income:

`\begin{aligned}\implies \textsf{Number of hours to work} & = \frac{\textsf{Cost of car}}{\textsf{hourly net income}}\\\\& = \sf (17500)/(13)\\\\& = \sf 1346.1538...\end{aligned}`

We have to round the number up to 1347 hours, as only $17,498 will be saved if 1346 hours are worked.

The average working week is approximately 40 hours, therefore to calculate how many weeks it would take to earn enough money to purchase the car, divide the number of hours by 40:

⇒ 1347 ÷ 40 = 33.675

So it would take 34 weeks, working an average of 40 hours a week and not spending any of the money earned, to save enough to purchase the car.
