Jenny wants to rent a truck for one day. She contacted two companies. Laguna’s Truck Rentals charges $20 plus $2 per mile. Salvatori’s Truck Rentals charges $3 per mile. After how many miles will the total cost for both companies be the same? A.4
B.6
C.20
D.60

For 20 miles the cost of both companies be the same.

Step-by-step explanation:

Consider the provided information.

Let x is the miles travel, Laguna's Truck Rentals charges $20 plus $2 per mile. Then the cost for the Laguna's truck is:

Now it is given that Salvatori's Truck Rentals charges $3 per mile.

As we know x is the miles travel, and Salvatori's Truck Rentals charges $3 per mile. Thus the total cost for Salvatori's Truck is:

We need to find the number of miles for which the total cost for both companies be the same.

For same cost  thus,

Subtract 2x from both sides.

Hence, for 20 miles the cost of both companies be the same.

Step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
