Prestige car rentals charge $44 per day plus 6 cents per mile to rent a mid sized vehicle. Gateway auto charges $35 per day plus

bulgar [2K]

Answer:

300 miles

Step-by-step explanation:

Let

x ----> the number of miles

y ----> the total cost for rent a car

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

Prestige car rentals

we have that

The slope is equal to $m=\$0.06\ per\ mile$

The y-intercept is $b=\$44$

therefore

$y=0.06x+44$ -----> equation A

Gateway auto

we have that

The slope is equal to $m=\$0.09\ per\ mile$

The y-intercept is $b=\$35$

therefore

$y=0.09x+35$ -----> equation B

For what number of miles both companies charge the same price>

Equate equation A and equation B

$0.09x+35=0.06x+44$

solve for x

$0.09x-0.06x=44-35\\0.03x=9\\x=300\ miles$
