Answer:

The approximate growth rate of the savings account is 2.5%

Step-by-step explanation:

Given the the function S(x) = 5, 000 * (1.025) ^ (0.7x)

From the function, we can see that part: (1.025). It presents for the growth factor or rate with the formula as:

(1 + r) where r is rate

So we have:

(1 + r) = 1.025

<=> r = 1.025 -1

<=> r = 0.025

In pecentage, we have the rare: 0.025 *100% = 2.5%

So the approximate growth rate of the savings account is 2.5%

Morgan has an investment worth $177,500. If his original investment was $50,000 and he received a 15% interest rate, how many ye

Illusion [34]

<h3>Morgan invested for 17 years</h3>

<em><u>Solution:</u></em>

From given,

Principal = $ 50, 000

Total amount = $ 177, 500

Rate of interest = 15 %

Number of years = ?

Interest amount = Total amount - principal

Interest amount = 177, 500 - 50, 000

Interest amount = 127500

<em><u>Use the formula,</u></em>

$Interest = \frac{p \times n \times r}{100}\\\\127500 = \frac{ 50000 \times n \times 15}{100}\\\\127500 = 500 \times 15 \times n\\\\75n = 1275\\\\n = 17$

Thus he invested for 17 years
