Answers:
- First Blank = 54
- Second Blank = 162
=============================================
Explanation:
The first blank represents the distance that corresponds to t = 1 hour.
We'll replace t with 1 to get...
d = 54t
d = 54*1
d = 54
Therefore, 54 goes in the first blank. It means that Isaac traveled 54 miles after 1 hour.
------------------
We repeat these steps for t = 3
d = 54*t
d = 54*3
d = 162
This means he traveled 162 miles after 3 hours
So 162 goes in the second blank
-------------------
Side note: your teacher wrote 180 but s/he should have written 108 instead because 54*2 = 108

Answer:
$461
Step-by-step explanation:
First, find the cost with the daily charge of $29.
Multiply 14 by 29, since the car was rented for 14 days:
14(29)
= 406
Find the cost with the distance traveled. Since there is only a charge after the first 100 km, subtract 100 from 320.
320 - 100
= 220
Find the charge by multiplying this by 0.25:
220(0.25)
= 55
Add this to the daily charge:
55 + 406
= 461
So, the cost will be $461
Answer:
A = 5t +7000
Step-by-step explanation:
Tim's rate of increasing altitude is 5 ft/min, so his change in altitude in t minutes is 5t.
If he started at 7000 ft, his altitude as a function of time is the sum of his initial altitude and his change in altitude:
A = 5t +7000
