Primo car rental agency charges $47 per day plus $0.30 per mile Ultimo car rental agency charges $26 per day plus $0.95 per mile
mario62 [17]

Answer:

The mileage is 2,300 miles

Step-by-step explanation:

Let x be the number of miles driven.

<u>Primo:</u>

$47 per day

$0.30 per mile \rightarrow $0.30x per x miles.

Total cost =\$(47+0.30x)

<u>Ultimo:</u>

$26 per day

$0.95 per mile \rightarrow $0.95x per x miles.

Total cost =\$(26+0.95x)

If Ultimo charge is three times the Primo charge, then

26+0.95x=3(47+0.30x)

Solve this equation:

26+0.95x=141+0.90x\\ \\0.95x-0.90x=141-26\\ \\0.05x=115\\ \\5x=11,500\\ \\x=2,300

50 PTS The table represents an exponential function.
GenaCL600 [577]

Answer:

B: 3/4

Step-by-step explanation:

Since we know this is an exponential function

y= ab^x

where a is the initial value and b is the growth rate or what we multiply by

For the first point x=1 and y = 3/2

3/2 = a b^1

3/2 = a*b

For the second  point x=2 and y = 9/8

9/8 = a b^2

Take the second equation over the first

9/8 = a b^2

-------------------

3/2 = a*b


3/4 = b

The growth rate is 3/4

That would also be know as the rate of change
