Answer:
c.) hourly rate
Step-by-step explanation:
The value the coefficient represents can often be learned from its units. The term 8t gives a value in currency units, since the expression 8t+20 is an amount that is to be paid. (We can only add like terms, so both 8t and 20 must have currency units.)
The value of t has units of hours, so the coefficient 8 must have units that are ...
8 currency units/hour
That is, multiplying by hours gives currency units.
In this context, a number with units of <em>currency units per hour</em> is most likely the hourly rate of the rental.

Thus, the rate of change per gallon of gas is 60 miles per gallon.
A motorcycle consumes 5 gallons of gas for 300 miles and 7 gallons for 420 miles.
<h3>What is
rate of change?</h3>
Rate of change is defined as the change in value with rest to the time is called rate of change.
Now,
Rate of change = Difference B/w volume (i.e. in gallons) /difference in miles
= 420-300/7-2
= 60 gallons/mile
Thus, The required rate of change per gallon of gas is 60 miles per gallon.

Answer:
A. 40.021
Step-by-step explanation:
Unlimited calls = $40
Text message = $0.021
NOTE:There is a difference between the value you gave for cost of text messages in the question and the values given in the group of answers. I will use $0.021 for cost of text messages since it is common to all answer choices.
Total cost = Cost of unlimited calls + cost of text messages
C = $40 + $0.021
= $40.021
Therefore, the equation which represent the total cost in dollars for a month is 40.021
A. 40.021
