Answer:
≈$12601.72
Step-by-step explanation:
Use the compounded interest formula:

In our case,
P = 3000
r = 8% = 0.08
n = 12 (months per year)
t = 18 (years in total)
Therefore, A ≈ $12601.72 (2.d.p.)
Answer:
Let g represent the cost of gas and e represent the cost of electricity.
150g + 520e = 84.20 ⇒ 7(150g + 520e = 84.20) ⇒ 1050g + 3640e = 576.80
210g + 405e = 82.35 ⇒ -5(210g + 405e = 82.35) ⇒ -1050g - 2025e = -411.75
1615e = 165.05
e = 0.10
150g + 520(0.10) = 84.20
150g + 52 = 84.20
140g = 32.20
g = 0.23
Answer: gas = $0.23, electricity = $0.10
