Answer:
1. $245.54
2. 810 KwH
3. 565 KwH
Step-by-step explanation:
1. the function solves for the amount of money that would be charged, and x represents KwH
x = 1986 KwH
y = (0.104)*(1986) + 39
y = 245.54
2. y = 123.24
123.24 = (0.104) * x +39
123.24-39 = 0.104x
84.24/(0.104) = x
x = 810 KwH
3. y = 97.76
97.76 = (0.104)*x + 39
97.76-39 = 0.104x
58.76 = 0.104x
58.76/0.104 = x
x = 565 KwH
