The lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.
<h3>Algebra</h3>
- Cost of higher-priced speaker = $170
- Cost of lower-priced speaker = $80
- Number of lower-priced speaker = 4x
- Number of higher-priced speaker = x
Higher-priced speaker = 170 × x
= 170x
Lower-priced speaker = 80 × 4x
= 320x
Total sales = $4,410
170x + 320x = 4,410
490x = 4,410
divide both sides by 490
x = 4,410 / 490
x = 9
So,
Number of lower-priced speaker = 4x
= 4 × 9
= 36
Number of higher-priced speaker = x
= 9
Therefore, the lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.

Answer:
Difference in total payback = $5734.64
Step-by-step explanation:
Formula for the simple interest payout,
Interest = 
P = Principal amount of loan
r = rate of interest (Annually)
t = Duration for the payment
Interest = 
= $13050
Total payable amount = 18000 + 13050
= $31050
Formula for the amount payable with compound interest,
Final amount = 
Here, t = Duration of investment
r = rate of interest (Annual)
n = Number of compounding per year
Payable amount = 
= 18000(1.089)⁴
= $25315.36
Difference in total payback = $31050 - $25315.36
= $5734.64
