Answer is : Price before increase is £250
Explaination:
Let the Original price of a ring = x
Increase price( g) = 30%
New price(n) = £325
x = ( 100*n)/ (100+g)
x= (100*325)/(100+30)
x= (200*325)/130
x= 250
Therefore price before increase is £250
Another method:
Given that after 30% increases,
the cost of the ring is £325 so we can assume that 130% (100+30) is £325.
Now, we have to form an expression in term of x where x represents the original cost :
130/100*x=325
Solving x
x= 250
So the original price or price before the increase is £250
25% as a fraction is 1/4 or 25/100 so as a decimal its 1/4 of 1 which is .25
Answer:
The locus is (x + 6)^2 + (y - 9)^2 = 100
Step-by-step explanation:
This is a circle with center (-6,9) and radius 10 units.
The general equation of a circle with center (a, b) and radius r is
(x - a)^2 + (y - b)^2 = r^2 so we insert the given values into this general equation to get the locus.
<h2>Answer </h2>
$96
<h2>Explanation</h2>
Let Margo's pay check
We know for our problem that she spends 0.25 of her pay check on a new dress, so she spent on the new dress. We also know that she spends 1/8 = 0.125 of her paycheck on shoes, so she pent on shows. Finally, we also now that she spends another $24 for total expenses of $60, so:
Now we can solve for to find how much was Margo's paycheck:
We can conclude that Margo's pay check was $96
