45. For customers generating their own solar power, ZG&E charges them $3 per month per kilowatt (kWh) for excess electricity

uranmaximum [27]

(A) The customer that owns a 3-kW system exports 120 kWh monthly to the grid will have the following bills for both companies:

For ZG&E that collects $3 per kWh on a monthly basis, the monthly bill will be

$120kWh\times\frac{\$3}{1kWh}=\$360$

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be

$\$20+(120kWh\times\frac{\$0.06}{1kWh})=\$27.2$

(B) The customer that owns a 5-kW system exports 300 kWh monthly to the grid will have the following bills for both companies:

For ZG&E that collects $3 per kWh on a monthly basis, the monthly bill will be

$300kWh\times\frac{\$3}{1kWh}=\$900$

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be

$\$20+(300kWh\times\frac{\$0.06}{1kWh})=\$38$

Question in attachment

denis-greek [22]

Answer:

(a) x + y = 63 OR 3x = 63

(b) 21

Step-by-step explanation:

Let Vijay's age be x and Ajay's be y.

Ajay is twice as old as Vijay

==> Ajay's age = 2 × Vijay's age

==> y = 2x

Sum of their ages = 63

==> x + y = 63

Substituting 2x for y:

==> x + 2x = 63

==> 3x = 63

Solving the above-obtained equation:

==> x = 21

Ajay's age = 2 times that of Vijay

==> y = 2x

==> y = 2×21

==> y = 42
