Step-by-step explanation:
There is a common ratio between consecutive term in the sequence, that is
÷
= 3 ÷
= 30 ÷ 3 = 300 ÷ 30 = 10
This indicates the sequence is geometric with n th term
= a
where a is the first term and r the common ratio
Here a = and r = 10 , thus
=
= ×
= 3 × ×
= 3 ×
Thus
= 3
→ C
Answer:
P = $300
r = 0.15
n = 12
$544.61 (to the nearest cent)
$524.70 (to the nearest cent)
Step-by-step explanation:
P = principal amount = $300
r = annual interest rate in decimal form = 15% = 15/100 = 0.15
n = number of times interest is compounded per unit t = 12
<u>How much she'll owe in 4 years</u>
P = 300
r = 0.15
n = 12
t = 4
= $544.61 (to the nearest cent)
<u>Yearly compounding interest rate</u>
<u>How much she'll owe in 4 years at yearly compounding interest</u>
= $524.70 (to the nearest cent)
