Question

The speed limit is 35 mph. Todd is stopped for

speeding and is fined $12 for every mile over
the speed limit. Write an equation for the fine
that Todd will have to pay. Use fas the
variable for the fine, and s for the speed of the
car.

Answer 1

An equation for the fine that Todd will have to pay is f = 12(s -35)

Explanation:

Given:

Speed limit = 35 mph

Fine amount for every mile over the speed limit = $12

To Find:

An equation for the fine that Todd will have to pay = ?

Solution:

The fine amount todd have to pay =f

Speed at which todd travelled = s

Then

It is said that that the fine amount $12 for every mile over the speed limit

The speed beyond the speed limit = (s -35)

Now the fine amount will be

f = 12(s -35)

f = 12s - 420
