The jewerly store is having a sale. Necklaces that were regulaey priced at $23.50 are on dale for $18.80. What is the percentage
AveGali [126]
What we need to do is find the difference between the two numbers to find the difference in price and then figure out what the percent of 23.5 that is

23.50-18.80=4.7

now we'll set up a proportion

4.7       x
----- = -----
23.5   100

then cross multiply and divide

100×4.7=470/23.5=20

the percent of decrease is 20%

I hope I've helped!

Dina invests $600 for 5 years at a rate of 2% per year compound interest.
Aleks [24]

Answer:

The value of this investment at the end of the 5 years is of $662.5.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

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

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Dina invests $600 for 5 years at a rate of 2% per year compound interest.

This means that P = 600, t = 5, r = 0.02, n = 1. Thus

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

A(t) = 600(1 + \frac{0.02}{1})^{t}

A(t) = 600(1.02)^t

Calculate the value of this investment at the end of the 5 years.

This is A(5). So

A(5) = 600(1.02)^5 = 662.5

The value of this investment at the end of the 5 years is of $662.5.
