Given:
Amount = 8700
Time = 3 years
Rate of interest = 24% per annum
To find:
The principal values.
Solution:
Formula for amount:

Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting
, we get




Divide both sides by 1.906624.



Therefore, the principal value is about 4563.04.
Answer: C(x) = 13x +95
Step-by-step explanation:
Here's the remainder of the question:
If C(x) represents the total cost and x represents the number of people attending the banquet, which equation shows the total cost? A C(x)=95x – 13 B C(x)=13x – 95 C C(x)=95x +13 D C(x)=13x +95
Based on the information given in the question, the total cost will be:
= 95 + 13(x)
= 95 + 13x
Therefore, the correct answer will be C(x)=13x +95
Make 3.5% out of 100:

3.5÷100=0.035. So the Answer is B. 0.035.
Shaun invested $176,250 into the new business.
Marcus invested half of the $940,000 so the amount that Shaun and Tristan invested is:
= 940,000 / 2
= $470,000
Shaun and Tristan invested in the ratio 3:5.
The amount that Shaun invested is:
<em>= (Ratio of Shaun / Sum of the ratios) x Amount both invested </em>
= (3 / (3 + 5 )) x 470,000
= 3/8 x 470,000
= $176,250
In conclusion, Shaun must have invested $176,250 into the business.

Step-by-step explanation:
We have xy = 28, x² + y² = 65 and x³ + y³ = 407.
Since (x + y)(x² - xy + y²) = x³ + y³,
x + y = (x³ + y³)/(x² + y² - xy)
= (407) / [(65) - (28)]
= 407 / 37
= 11.
Hence the sum of the numbers is 11.
