Manuel rented a truck for one day. There was a base fee of $15.99, and there was an additional charge of cents for each mile driven. Manuel had to pay $165.63 when he returned the truck. For how many miles did he drive the truck?

Let the number of miles driven be represented by x.

The total cost Manuel had to pay can be represented by the equation:
Total cost = Base fee + (cents per mile * number of miles driven)
165.63 = 15.99 + 0.99x

Solving for x, we get:
165.63 - 15.99 = 0.99x
149.64 = 0.99x
x = 149.64 / 0.99
x = 151.2

Manuel drove the truck for 151.2 miles.
