We must take into account the following change of units:

Applying the change of units we have that the electric consumption for 1 year is given by:

Then, the total cost is given by:
Answer:

Step-by-step explanation:
Percent error
(699-250)/699 x 100 = 64.23
A^2+b^2=c^2
24^2=12^2+x^2
sqrt(576-144)=x
sqrt(432)=x
12sqrt(3)=x
the answer is c
Answer:
6 months
Step-by-step explanation:
Find logarithm of both sides
log (3^x) = log 8
xlog3 = log8
x = log8/log3
x = 1.893
