Answer:
21.43 miles
Step-by-step explanation:
Let
x ---> the number of miles
y ---> the total cost of rent a car per day
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have
<em>sunshine rental company</em>
The slope is equal to

The y-intercept is equal to

substitute
----> equation A
<em> rent me company</em>
The slope is equal to

The y-intercept is equal to

substitute
----> equation B
equate equation A and equation B

solve for x

25% of x calories is 550 calories.
25% * x = 550
0.25x = 550
Divide both sides by 0.25
x = 2200
Answer: 2200 calories
Answer:
Step-by-step explanation:
