Write 250 in standard form

Mathematics
1 answer:
UNO [17]3 years ago
6 0
<span>To start, this has a value in the hundreds position: 200. This would be translated into "n * 10^2" in standard notation. We also see that we're working with more than 2 * 100 in this case, so the value that gives an "n" between 1 and 10 to set as a multiplier is 2.5. This gives "2.5 * 10^2" as a proper form.</span>

He needs to purchase some work clothes and notices that J.C. Penney is having a 25% off of your total purchase sale. He decides
SVETLANKA909090 [29]
First, lets determine the regular price of his purchase :

16.99 (3) + 34.99 (3) + 52.99 (2) + 5.99 (5) = 50.97 + 104.97 + 105.98 + 29.95 = 291.87

Therefore, the regular price of his purchase is $291.87 before sales tax.

If he receives 25% off of his total purchase, then the price is now :

291.87 * .75 = $218.90

We multiply by 75% because we are only paying 75% of the total purchase price since we received a 25% discount.

The total savings is 

291.87 - 218.90 = $72.97

If sales tax is 10%, the total purchase price after sales tax is :

218.90 * 1.10 = $240.79

The sales tax is $21.89 since

240.79 -218.90 = 21.89

If he pays with 3 $100 bills, we should receive :

300 - 240.79 = $59.21 

in change.
