Calculate the price with VAT of the following case.

AlekseyPX

Answer: $427140

Step-by-step explanation:

Firstly, we'll add MP to the profit and this will be:

= Rs 400000 + Rs 20000

= Rs 420000

Since there is a discount of 10%, this will then be:

= 420000 - (10% × 420000)

= 420000 - 42000

= $378000

With a VAT of 13%, then the final price will be:

= $378000 + (13% × $378000)

= $378000 + (0.13 × $378000)

= $378000 + $49140

= $427140

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric

allochka39001 [22]

I'm fairly certain that using that wire you can have the same area no matter what dimensions there are, but if you do the square root, or $\sqrt{}$ of 19,001,900 then you get 4359.11688. So your dimensions are 4359.11688 x 4359.11688. To get area, do length x width to get $1.9*1 0^{7}$ .

Hope this helped! If it did, please give me a good rating and mark me brainiest.

matrenka [14]

To find percent error, you subtract the actual number from your estimate, take the absolute value, and divide by the actual number.

l 96 - 118 l
l -22 l
l 22 l
l 22 l / 118
0.19% (this was rounded)

Hope this helps!
