Answer:
10 miles
Explanation:
Let's call the number of miles driven in a day "x". The total cost for Triangle Truck Rental can be expressed as:
Cost (Triangle) = $35 + 0.5x
The total cost for Circle Rent-A-Truck can be expressed as:
Cost (Circle) = $55 + 0.3x
We want to find the value of x such that Cost (Triangle) = Cost (Circle). So we can set the two expressions equal to each other and solve for x:
$35 + 0.5x = $55 + 0.3x
0.2x = $20
x = 100 miles
So the man would need to drive 100 miles in one day for both companies to have the same total cost.
