Inequality: 21d+25≤115
Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.
Step-by-step explanation:
Given,
Per day rent = $21.00
Per mile rent = $0.10
Miles to be driven by Jim = 250
Cost of 250 miles = 250*0.10 = $25
Amount Jim can spend = $115.00
Let,
d represent the number of days.
Per day rent*number of days + cost of 250 miles ≤ Total amount to spend
21d+25≤115
Subtracting 25 from both sides

Dividing both sides by 21

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

Answer:
The rate of change or slope m = -50
Step-by-step explanation:
The slope-intercept form of the line equation

where
- m is the rate of change or slope
Given that there is $500 in Holly's bank account.
Thus, the y-intercept b = 500
It is stated that she takes out $50 from her account each month but doesn't put money back in.
It means the rate of change or slope is decreasing.
Thus, the rate of change or slope m = -50
<u>EXTRA BONUS!</u>
We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form

y = -50x + 500
Here:
The slope m = -50
The y-intercept = 500
Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :

We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0

So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
Answer:
120 yards
Step-by-step explanation:
$9.75
Step-by-step explanation:
total amount _ Binoculars amount
$170_$105=$ 65
therefore before discount boots cost $65
After tax boots cost=15/100 ×$65
15/20× 13
195/20
=$9.75
