Enter the number of miles Johanna has left on her trip after 12 hours of driving
miles

Answer 1

Johanna has 304 miles on her trip after traveling for 12 hours

Explanation:

Here in this , we are interested in calculating the number of miles Johanna have left on her trip after driving for 12 hours.

To calculate the number of hours left, we simply make use of the given function. We make use of it by substituting the value of 12 for t in the given expression

Mathematically, the expression is given as;

F(t) = 1084 -65t

To know the number of miles left, we simply calculate f(12)

F(12) = 1084 -65(12)

F(12) = 1084 - 780

F(12) = 304
