Keith rented a truck for one day. There was a base fee of $15,95, and there was an additional charge of 74 cents for each mile driven. Keith had to pay $198.73 when he returned the truck. For how many miles did he drive the truck?
Let x be the number of miles driven.
The cost of the miles driven is 0.74 * x.
The cost of the truck rental is 15.95 + 0.74 * x.
So the equation is 15.95 +0.74 * x = 198.73.
Subtracting 15.95 from both sides we get 0.74 * x = 198.73 - 15.95 = 182.78.
Dividing both sides by 0.74 we get x = 182.78 / 0.74 = <<182.78/0.74=247>>247. Answer: \boxed{247}.
To find out the number of miles Keith drove the truck, we can subtract the base fee and divide the remaining amount by the additional charge per mile.
Let's start by subtracting the base fee from the total amount Keith had to pay:
$198.73 - $15.95 = $182.78
Now, let's divide this amount by the additional charge per mile:
$182.78 ÷ $0.74 = 247
Therefore, Keith drove the truck for 247 miles.
To find out how many miles Keith drove the truck, we can use the given information about the charges.
First, we need to determine the cost of the miles driven. We know that there was an additional charge of 74 cents for each mile driven. Let's represent the number of miles driven as "x".
So, the cost of the miles driven would be 0.74x.
Next, we add the base fee of $15.95 to the cost of the miles driven to get the total cost of renting the truck:
Total cost = base fee + cost of miles driven
Total cost = $15.95 + 0.74x
Since Keith had to pay $198.73 when he returned the truck, we can set up the following equation:
$198.73 = $15.95 + 0.74x
To isolate x, we can subtract $15.95 from both sides of the equation:
$198.73 - $15.95 = 0.74x
$182.78 = 0.74x
Now, we can solve for x by dividing both sides of the equation by 0.74:
$182.78 / 0.74 = x
The calculator gives us: x ≈ 247.32
Therefore, Keith drove the truck for approximately 247 miles.
