Answer:

Step-by-step explanation:
Let x be the distance driven, d-distance and C our constant.
Our information can be presented as:

#Subtracting equation 2 from 1:

Hence the fixed cost per mile driven,
is $0.20
To find the constant,
we substitute
in any of the equations:

Now, substituting our values in the linear equation:
#y=cost of driving, x=distance driven
Hence the linear equation for the cost of driving is y+0.2x+284
Hannah will earn $240 in 20 hours
Explanation: Since it tells you she earns $48 in 4 hours, you have to find how much she earns in 1 hour. So you do 48 divided by 4 (12) and that is how much she earns in 1 hour. Since the question is, how much does she earn in 20 hours, you multiply 12 x 20 and that equals 240 which means she earns $240 in 20 hours

Answer:
Current water in dam = 1,676.202 million m³ (Approx.)
Step-by-step explanation:
Given:
Storage capacity of dam = 2,536 million m³
Current water level = 65.4%
Find:
Current water in dam
Computation:
Current water in dam = Storage capacity of dam x Current water level
Current water in dam = 2,563 x 65.4%
Current water in dam = 1,676.202 million m³ (Approx.)
