$75 before tax. Disc: 10% Tax: 7%, Tip: 20% what’s the total?

ololo11 [35]

Answer:

$102.75

Step-by-step explanation:

Given the following question:

We are given a cost of 75 dollars and are being asked to find the total cost after adding a tip, tax, and disc to the cost. To find this answer we will use the formula to calculate percentages making sure we use 75 as our base for each addition to our total cost.

Formula to calculate percentages:

$\frac{p\times n}{100}$

First the disc:

$\frac{10\times 75}{100}$
$10\times75=750$
$750\div100=7.5$
$=7.5$

Next the tax:

$\frac{7\times75}{100}$
$7\times75=525$
$525\div100=5.25$
$=5.25$

Last but not least the tip:

$\frac{20\times75}{100}$
$20\times75=1500$
$1500\div100=15$
$=15$

Finally add:

$75+7.50+5.25+15=102.75$
$=102.75$

The total cost after adding the disc, tax, and the tip will be "$102.75."

Hope this helps.

19. Danielle earns a 7.25% commission on

EastWind [94]

Answer:

2,365.31

Step-by-step explanation:

since she earns $750 a week you subtract 750 from 1,076.25 which leaves you with 326.25 so you take the 326.25 an multiply it with 0.0725 and you get 2,365.3125 but you round it to 2,365.31, so that number is how much money worth of stuff she sold last week
