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.
7x - 1 + 6x - 1 = 180
13x - 2 = 180
13x = 182
x = 14
I = $ 1,200,000.00
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 1000000 × 0.03 × 40 = 1200000
I = $ 1,200,000.00
The simple interest accumulated
on a principal of $ 1,000,000.00
at a rate of 3% per year
for 40 years is $ 1,200,000.00.

Answer:
133.96 meters squared
Step-by-step explanation:
To calculate the area of a circle, simply multiply the radius squared, by pi.
A = pi x r^2
A = pi x 6.53^2
A = pi x 42.6409
A = 133.9603382
The area of the circle is approximately 133.96 meters squared.
Hope this helps! :)
