Question

A homeowner's electric bill for the month was $162.00 for 1,800 kilowatt hours of energy used. Write an equation that represents the cost in dollars of the electricity, y, and the number of kilowatt hours of energy used, x?

Answer 1

x is 1,800 kw energy used and y is $162 so a equation you can use

for every 1,800 kw of energy used you need to spend $162 so the equation would be

f(n)= 1,800 x 162^2
