Joan uses the function C(x) = 0.11x + 12 to calculate her monthly cost for electricity. • C(x) is the total cost (in dollars).
• x is the amount of electricity used (in kilowatt-hours).
Which of these statements are true? Select the three that apply.
A. Joan's fixed monthly cost for electricity use is $0.11.
B. The cost of electricity use increases $0.11 each month.
C. If Joan uses no electricity, her total cost for the month is $12.
D. Joan pays $12 for every kilowatt-hour of electricity that she uses.
E. The initial value represents the maximum cost per month for electricity.
F. A graph of the total cost for x ≥ 0 kilowatt-hours of energy used is a straight line.
G. The slope of the function C(x) represents the increase in cost for each kilowatt- hour used.
