Astoreowner orders 25 calculators that cost $30 each. the storeowner can sell each calculator for $41. the storeowner sold 22 calculators to customers. he had to return 3 calculators that were never sold and pay a $4 charge for each returned calculator (although the initial cost is refunded). what is the storeowner's profit?

The store owner's profit  is $230.

Step-by-step explanation:

The number of calculators ordered in total = 25

But out of this 25, the number of calculators returned = 3

So, the calculators that he actually paid for  = 25 - 3  = 22

The cost price of 1 calculator = $ 30

So, the cost price of 22 calculators = 22 x ( $ 30)  = $660

Also, he paid  $4 charge for each returned calculator.

So, the total charge paid for 3 calculators returned = 3 x (4$) = $12

Hence, his Total Cost Price

= Cost Price of 22 calculators+  Return charge of 3 cal.

= $660 + $12 =  $672

Also, The selling price of 1 calculator = $ 41

So, the selling price of 22 calculators = 22 x ( $41)  = $902

Hence, Total Selling  Price  = $902

PROFIT  = TOTAL SELLING PRICE - TOTAL COST PRICE

               =  $902 - $672 = $230

Hence, the store owner's profit  is $230.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
