The answer is that she had 48. Set it up as an equation with x as the amount of money she started with. x - 30 = 3/8x. That says, in words, "the amount of money she started with minus 30 for the dress left her with 3/8 of the money she started with. Solve for x by adding 30 to both sides and subtracting 3/8 from 8/8x (8/8 = 1). 8/8 - 3/8 = 5/8, so 5/8x = 30, multiply both sides by 8 to get 5x=240 and x = 48.
Answer:
32
Step-by-step explanation:
The sides of the quadrilateral are tangents to the circle.
Tangents drawn from an external point to the circle are congruent
5+5+4+4+3+3+4+4=32
The answer to the question would be 455

Answer
Find out the what is the percentage of this discount .
To prove
Formula
Discount = Marked price - selling price
As given
a jar of natural peanut butter normally costs $4.00 .
it's on sale for $3.60 .
thus
Marked price = $4.00
selling price = $3.60
put in the above formula
Discount = 4.00 - 3.60
= 0.4
Formula
put the value
Discount percentage = 10%
Option (a) is correct .
Hence proved
