Let's remember that V = lwh. If you are given two other measurements, you can multiply those two and divide V by that quantity to solve for the missing variable. Same process no matter the value:)
<u>The marked price of the article was $7865</u>
Answer:
solution given:
let marked price be x=?
discount =20%
vat=13%
selling price =$7232
we have
<u>discount amount=discount % of marked price</u>=20/100*x=0.2 x
and
<u>vat amount = vat% of selling price</u>=13/100*$7232=$940.16
we have
<u>Selling price with tax =marked price - discount amount + vat amount</u>
$7232=x-0.2x+$940.16
$7232-$940.16=x-0.2x
0.8x=$6291.84
x=$6291.84/0.8
x=<u>$7864.8</u>
Answer:
x = 44 and y = 4
Step-by-step explanation:
Given:
x - y = 40
2x + 3y = 100
Isolate for x in the first equation:
x = 40 + y
Sub x = 40 + y into the second equation and solve for y:
2(40 + y) + 3y = 100
80 + 2y + 3y = 100
5y = 20
y = 4
Sub y = 4 into the equation for x:
x = 40 + 4
x = 44
Therefore, x = 44 and y = 4
