Answer:
Step-by-step explanation:
So, we know that Jolene bought an initial $750.
We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.
So, we can use the compound interest formula, which is:
Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.
So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:
Add:
Since the stock was bought 3 years ago, the value now is t=3. So, substitute 3 for t and evaluate:
Evaluate. Use a calculator:
And we're done!
Formula: A = P(1 + r/n)^t
We have these variables:
P = 750
r/n = 0.055
t = 3
Substitute and simplify:
A = 750(1 + 0.055)^3
A = 750(1.055)^3
A = 880.68
Best of Luck!
Answer:
Total amount spent = $10,000
Cost of one HD headphones = $70
So, cost of 110 HD headphones = dollars
Hence, amount left to purchase basic headphones = dollars
So, the store can buy x headphones from $2300. Where x can be found by dividing 2300 by the cost of 1 headphones.
