Henry rented a truck for one day. There was a base fee of , and there was an additional charge of cents for each mile driven. Henry had to pay when he returned the truck. For how many miles did he drive the truck?

About that many.

To find out how many miles Henry drove the truck, we need to first determine the additional charge per mile and then divide the total additional charge Henry paid by that amount.

Let's assume the base fee is `B` dollars and the additional charge per mile is `C` cents.

Let's also assume Henry paid a total of `T` dollars when he returned the truck.

The additional charge per mile is given in cents, so we need to convert it to dollars by dividing by 100:

C = `cents per mile / 100`

Next, we can calculate the additional charge Henry paid by subtracting the base fee from the total payment:

A = T - B

Finally, we divide the additional charge by the charge per mile to find the number of miles driven:

Miles driven = A / C

To summarize:

1. Calculate the charge per mile: C = `cents per mile / 100`
2. Calculate the additional charge: A = T - B
3. Calculate the number of miles driven: Miles driven = A / C

Now we would need the values of the base fee (`B`), the total payment (`T`), and the charge per mile (`C`) to find the number of miles Henry drove.
