Laguana's Truck Rentals charges $20 plus $2 per mile.
Total cost of Laguana's Truck = .... (1)
Salvatori's truck rentals charges $3 per mile.
Total cost of Salvatori's truck = ... (2)
We need to find the number of hours after that the total cost for both companies will be the same.
Therefore, after 20 miles the total cost for both companies will be the same.

Step-by-step explanation:
Given
Required
The true statements
We have:
Substitute 10 for t
<em>Hence, (a) is true</em>
We have:
Substitute 740 for f(t)
Divide through by 740
Express 1 as 0.95^0
Cancel out the bases
Hence, the area had 740 acres initially;
(b) is true
We have:
Using the general formula
By comparison:
0.95 < 1 means that:
--- where r = rates
Collect like terms
Express as percentage
Hence, (c) is true
In (a)
Hence, (d) is false
In (c)
---- decrement
Hence, (e) is incorrect
