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

Answer:
10.9
Step-by-step explanation:
Formula = Number x 100
Percent = 6 x 100
55 = 10.91
Following shows the steps on how to derive this formula
Step 1: If 55% of a number is 6, then what is 100% of that number? Setup the equation.
6
55% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
55Y = 6 x 100
55Y = 600
Y = 600
100 = 10.91
