Answer:
Interest= $423.59
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $6,000
Number of periods (n)= 3 years
Interest rate (i)= 2.3% = 0.023
<u>To calculate the Future Value, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 6,000*(1.023^3)
FV= $6,423.59
<u>Now, the interest earned:</u>
<u />
Interest= 6,423.59 - 6,000
Interest= $423.59

Answer:
Q = 3
Step-by-step explanation:
3 * P + 7 * Q + 15 * R = 102
7Q = 102 - 3P - 15R
Q = (102 - 3P - 15R)/7
Try P = 2; R = 3
Q = 51/7 not an integer
Try P = 2; R = 5
Q = 21/7 = 3
Solution: P = 2; Q = 3; R = 5
Answer: Q = 3
