Answer:
Option B is correct.
Total time that Antony's family spent driving to and from the lake = 8.5 hr
Step-by-step explanation:
Using time formula:
As per the given statement: Anton's family drove 216 mi to the lake averaging 48 mi/hr .On the return trip home they averaged 54 mi/hr
⇒ Anton's family drove total distance = 216 mi
Speed of Antony's family driving to lake = 48 mi/hr
Time taken to driving to lake = 
Now,
Speed of Antony's family driving from lake = 54 mi/hr
Time taken to driving from lake = 
Total time spent driving to and from the lake = 4 + 4.5 = 8.5 hr.
therefore, the total time that Antony's family spent driving to and from the lake was, 8.5 hr

Answer:
x intercept is (3.75, 0) and y intercept is (0, 2.5)
Step-by-step explanation:
4x + 6y - 15 = 0
x int = (3.75, 0)
0*6 = 0
4x - 15 = 0
0 + 15 = 4x = 15
15/4 = 4x
x = 3 3/4 or 3.75
y int = (0, 2.5)
0*4 = 0
6y - 15 = 0
15 = 6y
15/6 = y
y = 2.5
The formular which can be used to obtain the monthly charges as a function of the number of cheques written is 9.75 + 0.15x
Charges on account :
- Charge per check written = $0.15
- Monthly services charge = $9.75
The total amount charged monthly, F as a function of the number of cheques written, x can be expressed thus :
Monthly service charge + (charge per check × number of cheques written)
F(x) = 9.75 + 0.15x
Therefore, the charge function which can be used to calculate the total monthly charge on his account ls F(x) = 9.75 + 0.15x
