$300 - $140 = $160

Now we do $160 divided by $40

That means she bought 4 dresses for $40 dollars each

500 principal earning 3% compound monthly, after 10 years.
mamaluj [8]

Answer:

D. $674.68

Step-by-step explanation:

We will use the well known equation for compound interest

A = P(1 + \frac{r}{n})^{nt}

Where

  • A is the final total
  • P is the principal amount (starting total)
  • r is the interest rate as a decimal
  • n is the number of times the interest is compounded each year
  • t the number of years

Plugging in what we know from the question:

A = 500(1+\frac{0.03}{12})^{12 \times 10}\\A = 500(1.34935355)\\A = 674.68

So the answer is D.

Hope this helps!

Four thrids times the sum of a number 8 is 24. what is the numver​
guajiro [1.7K]

Answer:

The number is 10

Step-by-step explanation:

Let the number be x.

four thirds times = 4/3

According to the statement:

four thrids times the sum of a number and 8 is 24

4/3 *(x+8)= 24

Move  3 to the R.H.S and Multiply 4 with the parenthesis.

4x+32=24*3

4x+32=72

Move constant to the R.H.S

4x=72-32

4x=40

Divide both the terms by 4

4x/4=40/4

x=10

Therefore the number is 10....
