Step-by-step explanation:
4(a-3)=22
a-3=4-22
a-3=18
a=18+3
a=21
5(x-6)=65
x-6=65-5
x-6=60
×=60+6
x=66

(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

(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

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be
Type A = $5.75 per pound
Type B = $4.55 per pound
1 set → 1 pound of Type A + 4 pounds of type B
1 set → 5.75 + 4(4.55)
1 set → $23.95
Number of sets = $526.90 ÷ 23.59 = 22
1 set → 1 pound of Type A
22 sets → 1 x 22 = 22 pounds of type A
Answer: 22 pounds of Type A
