A public beach in Florida charges non residents $8 per day for a fishing license and $2.50 per day for live bait. Florida reside

melamori03 [73]

For a non-resident:

$C_{nr}=8d+2.5d=10.5d$

For a resident:

$C_{r}=114+1d$

We want to know the number of days $d$ such that the two costs are equal ie $\{d|C_{nr}(d)=C_{r}(d)\}$

To do this set the two costs equal to each other:

$C_{nr}=C_{r}$

$10.5d=114+1d$

And solve for d:

$10.5d-1d=114+1d-1d$

$9.5d=114$

$d=\frac{114}{9.5}$

$d=12$

The costs will be equal when a resident and a non-resident each use the beach for 12 days.

Let

T--------> the total price of the vehicle

x--------> amount paid

y--------> amount owed

we know that

the total cost of the vehicle is equal to the amount paid plus the amount owed

$T=x+y$

Find the amount paid

$x=567*48\\ x=27,216\ dollars$

$T=x+y\\ T=27,216+1,250\\ T=28,466\ dollars$

therefore

the answer is

the total price of the vehicle is $28,466\ dollars$
